Which rate expression suggests an over all order of 2.5 for the reaction involving substances X, Y, Z?

Options

A. Rate `=k[X][Y][Z]^(2.5)`
B. Rate `=k[X]^(0.5)[Y]^0.5[Z]^0.5`
C. Rate `=k[X]^(1.5)[Y][Z]^0`
D. Rate `=k[X][Y]^0//[Z]^2`

Explanation

Order of reaction is sum of the power raised on concentration terms to express rate expression `1.5 + 1 + 0 = 2.5`
