Question

A catalyst works by decreasing the activation energy needed for a reaction.
True
False

Answer 1

Catalysts provide an alternate pathway for the reaction to occur, which has a lower activation energy.
As the Ea is reduced, the number of molecules with more energy than the Ea is higher, so faster reaction!

so true decreasing the activation energy required for a reaction

Answer 2

Thanks!

np bio is easy for me

Answer 4

This is Chemistry xD
