C is the answer
Not sure tho I have not revised kinetics
Since k2 is bigger than k1 the rxn is readily happening and P.E should be lowering so AB+I should be higher than A+P
I am bit confused between C and D tho
since k1 is small, its activation energy Ea1, must be higher than Ea2. (distance b/w IAB and top of curve = Ea1 > distance b/w AB + I and top of next curve = Ea2).
This eliminates option D.
also, since the reaction is exothermic, the final energy must be lower than the initial energy, this eliminates b.
Now between a and c how doyou decide? :D
Ohhh that makes a lot more sense
A
Since it’s said much smaller
yea the rds should have the highest Ea, also the 'fast' step should have a low energy too.
