Which definition best describes the term activation energy?

Question

Which definition best describes the term "activation energy"?  
a) The energy required to remove an electron from a gaseous atom
b) The minimum kinetic energy that particles must possess for a chemical reaction to occur
c) The energy of motion
d) The energy required to separate ions in a crystalline solid  
I think the answer is C because activation energy is the amount of energy required for a chemical reaction to take place. It represents the starting energy needed before the reaction can proceed. If there is no activation energy, the reaction won't occur. Additionally, if the energy of the colliding molecules is less than the activation energy, the reaction will also not happen.  
Is this correct? Thanks! 🙂

Your description shows you understand the concept,

but you should have translated that to choice B.

A is the definition for ionization energy

C is the definition of kinetic energy

D could be the definition of lattice energy.

Describe Activation Energy

Mr. Leone Miller · Answer

It is (B) the minimum
kinetic energy
that particles
must possess
for a chemical
reaction to
occur
.Note that it is the introduction of a catalyst that lowers the activation energy thereby creating a new reaction pathway.Take care

Which Definition

Grady Ebert · Answer

most chemical reactions obey one of three differential rate laws. Each rate law contains a constant, k, called the rate constant. The units for the rate constant depend upon the rate law, because the rate always has units of mole L-1 sec-1 and the concentration always has units of mole L-1...Zero-Order Reaction... For a zero-order reaction, the rate of reaction is a constant.... When the limiting reactant is completely consumed, the reaction abrupts stops
