Which of the following graphs are correct for a second order reaction: (where symbols have their usual meanings)

Options

A. (i) and (iii)
B. (i) and (iv)
C. (ii) and (iii)
D. (ii) and (iv)

Answer

B

Explanation

For a second order reaction,
Rate `=-(dC)/(dt)=KxxC^(2)`
Also `t_((1)/(2))propC_(0)^((1)/(2))`. So, `t_((1)/(2))xxc_(0)=` constant. Therefore,
Correct graphs are
