The rate of a certain reaction is given by, rate = k [H+]n. The rate increases 100 times when the pH changes from 3 to 1. The order (n) of the reaction is
2

1.5
The correct statement regarding the following energy diagrams is
Reaction M is faster and less exothermic than reaction N
Reaction M is slower and less exothermic than reaction N
Reaction M is faster and more exothermic than reaction N
Reaction M is slower and more exothermic than reaction N
C.
Reaction M is faster and more exothermic than reaction N
In reaction M, there is only an intermediate step, so it is a fast reaction. Also, energy of product is much lesser than that of the reactant, as compared to as shown in reaction N. Thus, reaction M is faster and more exothermic than reaction N.
