for the reaction, `2A + B rarr 3C + D`, which of the following does not express the reaction rate

Options

A. `(d[D])/(d t)`
B. `-(d[A])/(2d t)`
C. `-(d[C])/(3d t)`
D. `-(d[B])/(d t)`

Answer

C

Explanation

The rate of reaction is
`= -(1)/(2) (d[A])/(d t) = -(d[B])/(d t) = (1)/(3)(d[C])/(d t) = (d[D])/(d t)`
