How do changed in temperature and activation energy compare in how they affect reaction rate?
Changes in temperature and activation energy have opposite effects on reaction rate.
How do changes in temperature and activation energy compare in how they affect reaction rate Apex?
Changes in temperature and activation energy have opposite effects on reaction rate.
How does activation energy affect the progress affect the progress of a reaction?
The reaction will not occur unless the activation energy is met.
How does activation energy affect the length of a reaction?
as activation energy decreases, reaction will finish faster (length of reaction decreases)
How do enzymes affect activation energy and reaction temperature?
As kinetic energy, and therefore temperature increases, the number of effective collisions which result in sufficient activation energy also increases, which is why reactions happen at a faster rate at higher temperatures.
How does activation energy affect chemical reactions?
The Arrhenius equation is: Ea = -RT ln(k/A) where Ea - activation energy R - universal gas constant ln - logarithm k - speed constant T - temperature in kelvins
Does a catalyst affect a reaction activation energy?
yes. lowers it.
Why does catalyst affect reaction speed?
The activation energy is reduced.
How does a temperature increase affect collision between molecules?
The number of collisions with enough energy to react increases.
Enzymes increase the rate of a reaction by doing what?
An enzyme is a catalyst that speeds up a chemical reaction. It functions by lowering the activation energy required for a reaction to occur, and by reducing the activation energy, the reaction speeds up.
What is activation energy How does a catalyst affect activation energy?
Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.Improvement:A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.* = as a result of the interaction of the reagents with the catalyst.
How does the addition of a catalyst affect the energy activation of a chemical reaction?
It lowers it, so the reaction is faster.
