Question

Effect of catalyst,temperature on rate of reaction (how and why?)

Answer 1

Answer:

With an increase in temperature, there is an increase in energy that can be converted into activation energy in a collision, and that will increase the reaction rate. ... When a catalyst is added, the activation energy is lowered because the catalyst provides a new reaction pathway with lower activation energy.
