Explanation / Answer

7)
A: reactant
B: transition state
C: intermediate
D: transition state
E: intermediate
F: transition state
G: product

b)
There are 3 elementary steps
A—> C
C—>E
E—>G

C)
product has more energy than reactant since G is at higher level than A
So, energy is absorbed in the process
so, it is endothermic
