The reaction $A k$ Product, is zero order while the reaction $B k$ Product, is first order reaction. For what initial concentration of A are the half lives of the two reactions equal?

Options:

Answer:

Solution:

For zero-order reaction,

$x = k t$ ; $\frac{a}{2} = k \times t_{\frac{1}{2}}$

for first order reaction

$t_{\frac{1}{2}} = \frac{l n 2}{k}; \frac{a}{2 k} = \frac{l n 2}{k}$

So, $a = ln 4 M$ .
