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

Options

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

Answer

D

Explanation

d) `(-d[C])/(3dt)` does not represent the reaction rate because the molar concentration of the products increases and not decreases.
