In a chemical reaction, activation energy increases the of the reactants. this outcome causes the particles to collide, which results in the of new products.

energy, formation

Explanation:

Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.

A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy.

More molecules will acquire enough energy to cross the energy barrier and more effective collisions will result leading to the formation of new products.

well we can't tell you because we cant see the time give a screen shot or something.
