What will be the order of reaction and rate constant for a chemical change having `log t_(50%)` versue log concentration of `(a)` curves as:

Options

A. `0, 1//2`
B. `1, 1`
C. `2, 2`
D. `3, 1`

Answer

A

Explanation

by graph we can say `log t_(1//2) = log a t_(1//2) = a` …(1)
`t_(1//2) prop a` then zero order Rxn `" "k xx t_(1//2) =` …(2)
theta `k = (1)/(2)`
