Increases reaction rate.
a catalyst can affect the rate of a reaction. speeding it up.
Changing temperatures has a dramatic affect on the rate of chemical reaction. As an example for every 10 degrees you raise the environment the reaction doubles (to a certain degree)
They can all affect the rate of a chemical reaction.
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
It leads to more frequent collisions, which increase reaction rate.
That is precisely correct.
it will increase the time of the chemical reaction
a catalyst can affect the rate of a reaction. speeding it up.
There are numerous ways to affect the speed of a chemical reaction. They are add a catalyst, increase the concentration of reactants, increase surface area of reactants, increase pressure, and increase the energy in the environment around the reaction.

The concentration of reactants is changed.

A chemical reaction need an activation energy to start.
Enzymes affect the speed of reactions predominantly. In some instances in which more than one reaction is possible, enzymes increase the speed of the normally slower reaction enough to make it predominate, while the other possible reaction is effectively suppressed.
At excessive temperatures, enzymes usually denature or break down into other molecules, thus failing to preform their specific function.Other than that, heat does not affect enzymes much but it does increase the speed of the reaction.
It leads to more frequent collisions, which increase reaction rate.
