Plz explain these

Energy produced/stored in a compound is directly proportional to the percentage carbon in a compound.
So B has greatest percentage composition of carbon for example:
36÷(36+8) *100
=82%

why b?

Note that except for B, the dipoles for the other 3 options can be viewed as cancelling each other out

[khadijaimran]

the ans is B. whats wrong with D?

Why isn’t the answer A?View attachment 64015

Because increasing the concentration means that you are increasing the number of collisions, but those collisions can be either successful or not while an increase in the temperature ensures that the number of successful collisions will be more.
Not sure if my explanation is correct, so please correct me if it's wrong.

C-I bond is weaker so breaks quicker than C-Br

Equilibrium constant is only effected by temp...temp is same so it is also same
