What else can I help you with?
What depends to some extent on temperature?
Viscosity, solubility, and reaction rates are all examples of properties that can be influenced by temperature. Generally, as temperature increases, these properties also tend to increase as particles gain more energy and move more quickly.
What affect rates does a enzyme catalyzed reaction have?
Enzyme-catalyzed reactions generally increase the rate of a reaction by lowering the activation energy required for the reaction to occur. Enzymes do this by stabilizing the transition state of the reaction, allowing it to proceed more easily and quickly. Additionally, enzymes can enhance reaction specificity and selectivity, making them very efficient catalysts.
A student performs a reaction twice. in the second trial she raises the temperature by 20 degrees C and notices that the reaction takes place more quickly. is the reaction endothermic?
Yes, raising the temperature and causing the reaction to occur more quickly is indicative of an endothermic reaction. This is because endothermic reactions require energy input in the form of heat to proceed faster.
Would a single sugar cube or an equal mass of graduated sugar crystals react more quickly in a chemical reaction?
The same mass of sugar crystals would react more quickly in a chemical reaction compared to a single sugar cube. This is because the increased surface area of the sugar crystals allows for more efficient contact with the reactants, leading to a faster reaction rate.
How does catalyst enable a reaction to happen more quickly?
The work done by the catalyst is to change the mechanism of a reaction, actually the alternate way using the catalyst needs lesser energy to the same reaction without the catalyst.

Why do front breaks wear out more quickly?
The front brakes generally do most of the work.
How does an enzyme speed up its reaction?
Enzymes speed up a reaction by lowering the activation energy. This is the amount of energy required to start the reaction. By lowering the activation energy, the reaction can proceed much more quickly.
What does the reaction rate indicate about a particular chemical reaction?
The reaction rate indicates how quickly the reactants are being converted into products in a chemical reaction. A faster reaction rate means the reaction is proceeding more rapidly, while a slower reaction rate indicates the reaction is proceeding more slowly.
Is reaction time in born or made?
A reaction time is born but is made at the same time. While you grow older and use your reaction more, your reaction time will become faster and better. So, your reaction time isn't born nor made.
What are the factors affecting rate of reactoin?
There are 4 factors affecting rate: - Surface area -Temperature - Catalysts -Concentration If the surface area is increased the reaction rate will increase due to more particles being exposed to the reacting chemical, the more particles colliding the quicker the reaction will happen. Temperature causes particles to speed up or slow down, for example in a gas particles are moving very quickly, and therefore they collide more often, this would mean that a reaction would happen quickly since reaction depends on the amount of collisions as well as the strength of collisions. Catalysts are added substances into reactions which only help to speed up the reaction, they are not changed in the reaction and remain the same after the reaction has occurred. If concentration is increased more particles are given the chance to collide, so once again, with more collisions the more quickly a reaction occurs.
How is changing the rate of chemical reaction useful to us?
ECONOMICS AND SAFETY. A reaction is not as useful if it say takes a week. That would tie up a reactor for a long time resulting in more capital equipment being needed. A reaction that proceeds quickly is much more desirable and also ensures that customers are not let down. A reaction that proceeds too quickly can get out of control and be very unsafe.
How does an enzyme influence the rate of a biological reaction?
Enzymes speed up biological reactions by lowering the activation energy needed for the reaction to occur. This allows the reaction to happen more quickly and efficiently.
