What change would not affect the relative rate of action of enzyme x?
increase of temp in 70- 80 degrees
Who said increase in pressure then temp will increase?
Albert Einstein
What is the effect of temperature on the rate of evoporation?
Higher temp = higher rate of evaporation
How can you tell a chemicall reaction has happened?
The most obvious event to look for to indicate a chemical reaction is the production of heat. All chemical reactions produce heat.
What is the result of increasing the temp of a gas?
The kinetic energy will increase
What are Ways to change the rate of a chemical reaction?
1. Increase the temp 2. Increase surface area 3. Increase the pressure of the system
What effect dose temperature have on reaction rate?
It depends on the original temperature, but the rule of thumb is that near normal room temperature, raising the temperature by ten degrees will roughly double the reaction rate.
What factors change the rate of chemical reaction?
Adding a catalyst to the process will make the chemical reaction go faster. Also, the temperation, concentration, state of matter and pressure will affect the rate of the chemical reaction.
What are rates of reaction influenced by?
Temperature (rate increases with temp increase) Pressure (rate again increases with press increase) Concentration (rate increases with concentration increase) Particle size (rate increases with smaller particles) Catalyst increases rate.
What could be added to an enzyme-catalyzed reaction to decrease its rate?
Decreasing the temperature of the system
Troposphere increase or decrease in air temp?
The temperature of the Troposphere generally decreases as altitude increases.
When Increasing the concentration and increasing the temp both increase the reaction rates based on which physical phenomenon?
The kinetic energy of the reactants. By increasing the concentration, there are more reactant particles available for the reaction, and increasing the temperature increases the kinetic energy so the reactants come in contact more often, and the reaction rate increases.
What change would not affect the relative rate of action of enzyme x?
increase of temp in 70- 80 degrees
What conditions increase the rate of chemical reaction?
Many factors can and do increase the rate of chemical reactions. The most obvious is an increase in temperature, although too large an increase can breakdown the reactants. Other factors include catalysts, enzymes, pressure, concentration of reactants , surface area and other forms of energy (UV is an example).
Will a darker pool liner cause more water evaporation?
A dark pool liner might cause a very small increase in water evaporation, but nothing significant. The dark pool liner will raise the water temp a bit which, in turn, may increase the evaporation rate. But, the evaporation rate is much more dependent upon the air temperature and humidity than on the water temp, so the increase in water temp would only have a very small effect on the overall or net water evaporation rate. Hope this helps ... yes, it will, and it could be a significant increase.
What is the temp of oranges?
it has many temp because it can be changed by a reaction of the change in temp
What are 4 things that can affect the rate of a reaction?
1. Temperature: Depending on the temperature of the reactants, the reaction rate will differ. The higher the temperature (or the hotter the reactant is), the quicker the reaction will occur. The cooler the reactant is, the longer it will take for a reaction to take place. The heat causes the particles to move quickly, and due to the Collision Theory, which states that in order for a reaction to occur, molecules must collide, the particles will be more likely to bump into each other, and so the reaction will occur faster.2. Concentration: The higher the concentration of a reactant, the quicker the reaction will occur. This means that there are more particles of that particular substance, meaning it will collide more frequently into the particles of the other reactant. This increases the reactant rate because the more concentrated a reactant is, it means that the less space there is between the two reactants.3. Surface Area: Basically, the more particles that are exposed during the experiment, the faster the reaction will occur. The more the particles are exposed, the faster it is for the other reactant to collide into the particles, meaning the reaction rate will increase.4. Catalysts: Catalysts are substances that increase the rate of reaction by speeding up the reaction without being used up in the reaction. It does not affect the reactants in any other way than making them collide into each other more frequently, and it doesn't affect the product (or products) produced
