A reaction in which reactants (R) are converted into products (P) follows second order kinetics.If concentration of R is increased by four times, what will be the increase in the rate of formation of P?
(a) 9 times
(b) 4 times
(c) 16 times
(d) 8 times
Answer : (c) 16 times
Explanation :
For the reaction,
Reactants(R) → Product(P)
It follows 2nd order kinetic.
For a second order reaction,
rate = k [R]²
If the concentration of reactant (R) is increased by four times,
rate = k [4R]² =16k [R]²
Hence, the rate of formation of P increases by 16 times.
c) 16 times
