Help with Chem 12 homework?

I understand what activation energy is, but I don't know how I'm supposed to know what the question asks

Discuss the activation energy for the collision of molecular chlorine (Cl2) with molecular hydrogen (H2), and for the collision of atomic chlorine (Cl) with molecular hydrogen (H2). Which reaction must have the greater activation energy, and what evidence can be used to support your argument?

In your textbook there should be a table where you can find values for delta G, delta H, delta S and also Ea (activation enrgy) and you use that table to figure out which gives you greater activation energy.
I don't have the values at hand, but my guess is Cl2 + H2 will have a higher activation energy than Cl + H2, because Cl2 is much more [stable] than Cl. More reactive molecules requires lower activation energy.

Use electron shells as proof, I think.

In your own opinion, explain which has the greater activation energy.

Some people are so smart that they are dumb.
