When the rate determined by the change in concentration of two different reactants, then the kinetic equation may be expressed as

Options

A. `k_(2) = (2.303)/((a-b)t)log.((a-x)b)/((b-x)a)`
B. `k_(2) = (2.303)/((a-b)t)log.((a-x))/((b+x))`
C. `k_(2) = (2.303)/((a-b)t)log.((a-x))/((b-x))`
D. `k_(2) = (1)/(t) xx (x)/((a-x))`

Answer

A

Explanation

Two different reactants means second order reaction. For second order reaction.
