Why are catalysts reaction specific Iethey are different for different chemical reactions How catalyst modifies the rate of a chemical reaction Why don't they take part react in the chemical reaction?
Catalysis reaction are the generic potential energy. Chemical reactions is the process that leads to the transformation of a set chemical.
Why do you want to control the rate of a chemical reaction?
There are several reasons you might want to control the rate of a chemical reaction: A) the reaction occurs very slowly in normal conditions (like rusting) but you want to do it more quickly (like fake antiques). B) the reaction normally occurs quickly, but you want to slow it down so it lasts longer (like in some batteries) C) most reactions can be more or less efficient depending on the reaction rate and other conditions, often (like in engines) you want the reaction rate that will be most efficient under a set of given conditions. D) some reactions might be more difficult to manage unless they are slowed down.
What three things can affect the way enzymes work and explain how each factor affects an enzyme activity?
Enzymes act as biological catalysts which means they speed up chemical reactions in living things. 3 things that affect its rate would be temperature, pH, and regulatory proteins that turn them on or off.
What is the importance of enzymes?
Enzymes break down proteins for use in the body, and they're to speed up the reaction of the product.eg - photosynthesis enzymes are used to speed up the reaction to make it into glucose and oxygen.Enzymes (pronounced /ˈɛnzaɪmz/) are proteins that catalyze (i.e., increase the ratesof) chemical reactions.[1][2] In enzymatic reactions, the molecules at the beginning of the process are called substrates, and they are converted into different molecules, called the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.
How do enzymes affect reactions in living cells?
Enzymes are biological molecules that catalyze (i.e., increase the rates of) chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell. Enzymes are known to catalyze about 4,000 biochemical reactions.
Does temperature affect reaction time?
Temperature can affect the length of time a reaction takes (reaction rate) because atomic and molecular activity are somewhat temperature dependent. Certainly the mobility of molecules, atoms or ions has a temperature component. The fact that something like dynamite may be packed in ice won't prevent an explosion if it is set off, but many, many chemical reactions have reaction rates that are temperature dependent. The applied chemistry of the preparation of food broadly exemplifies this phenomenon. In chemistry, the Arrhenius equation speaks directly to temperature dependence of a reaction. Indeed, temperature is a factor in particle behavior as is set down in Boltzman distribution. Links are provided for some further reading.
How do enzymes affect chemical reaction?
Usually enzymes have the role to catalyse a reaction. That means they aren't changed at all, but they influence the mechanism to reduce the activation energy (the energy needed for the reaction). The reaction is therefore performed more easily. To put it very simply: It speeds up a chemical reaction.
Why is it useful to designate a standard temperature and pressure?
As you may soon learn in thermodynamics, the reaction rate constant, k, depends on the activation energy, temperature and pressure (if gaseous) of the system. Therefore, to unify reaction rates and rate constants, a standard temperature and pressure (such as STP and SATP) is designated to make sure when one chemist publishes a certain set of results, it could be accurately reproduced using the exact same reaction circumstances.
What controls the rate of chemical reaction in human body?
In the human body enzymes control the rates of chemical reactions. Enzymes speed up reactions by lowering the activation energy, or the amount of energy required for the reaction to occur.
What does thermo mean?
In Greek "thérmé" means "heat."Examples:-Thermals are rising columns of heated air.-Thermometers measure temperature (-temperature is a measure of heat, heat is energy.)-Isotherm refers to a series of values at equal temperature.In science and engineering: 'Thermo' is short for 'Thermodynamics.'Thermodynamic analysis provides information on the equilibrium configuration of a system. It predicts whether or not a chemical reaction (or set of reactions) is energetically favorable.It does not provide a basis for the rate at which the reaction takes place, this is provided by Kinetics. (Note: If the rate of reaction is slow enough, that reaction can be considered to not occur for all practical purposes.)
How fast does Jell-O thaw?
Jello thaws at a rate according to the temperature of the environment into which it is set. Warmer temperature will make it thaw faster than cooler temperature.
What is the recommend dose of enzymes for a baby?
There are no set standards for enzymes for babies.

Catalysis reaction are the generic potential energy. Chemical reactions is the process that leads to the transformation of a set chemical.
What are three statements that describe an enzyme?
1. It is not used up and does not change shape in a reaction. 2. It is used to speed up a reaction 3. Will only bind to another molecule as long as the enzyme substrate complex can form(see lock and key theory)
How could you determine the effect of temperature of the rate of the chemical reaction between baking soda and vinegar?
For this you would need a stopwatch and the ingredients for the reaction. Now take vinegar in a beaker and keep the stopwatch in one hand. take a pinch of baking soda in the other hand. Now drop it in the vinegar solution and simultaneously start the stopwatch. Note the time taken for the bubbling to stop completely. Now raise the temperature and repeat the same experiment. Do this for 5 set of reading by raising the temperature 5 degrees each time. Now do this by decreasing the temperature 5 degrees. Tabulate the data and think about the answer.

What temperature should the central air be set to?
There is no set temperature that the central air should be set to. Most people choose to set this temperature to about 70 degrees Fahrenheit.
