Which of the following rate laws has an overall order of `0.5` for reaction involving substances `x, y` and `z` ?

Options

A. Rate `= K(C_(x))(C_(y))(C_(z))`
B. Rate `= K(C_(x))^(0.5)(C_(y))^(0.5)(C_(z))^(0.5)`
C. Rate `= K(C_(x))^(1.5)(Cy)^(-1)(Cz)^(0)`
D. Rate `= K(C_(x))(C_(z))^(n)//(C_(y))^(2)`

Answer

C

Explanation

Order of reaction is sum of the power raised on concentration terms to express rate expression.
