For a zero order reaction

Options:

Answer:

Solution:

For a zero order reaction rate, $- \frac{d [ R ]}{d t} = k$ On integrating, we get $[R] = - k t + [C]$ When $t = 0, [R] = [R_{0}]$ $∴ [C] = [R_{0}]$ $∴ [R] = - k t + [R_{0}]$ When, $t = t_{1/2}, [R] = \frac{[ R _{0} ]}{2}$ $∴ \frac{[ R _{0} ]}{2} - [R_{0}] = - k t_{1/2}$ $∴ t_{1/2} = \frac{[ R _{0} ]}{2 k}$ $t_{1/2} \propto [R_{0}]$
