Question

A reaction in which reactant (R) are converted into products (P) follows second order kinetics. If concentration of R is increased by four times, what awill be the increase in the rate of formation of P?

• A. 9 times
• B. 4 times
• C. 16 times
• D. 8 times

Answer 1

Answer: (C)

16 times

Answer 2

$R \rightarrow P$

For a second order reaction rate $= k\lbrack R\rbrack^{2}$

If conc. Of R is increased by four times, rate

$= k\lbrack 4R\rbrack^{2}$

Hence the rate of formation of P increases by 16 times.
