When two reactants, A and B are mixed to give products C and D, the reaction quotient Q, at the initial stages of the reaction.

Options

A. is zero
B. decreases with time
C. is independent of time
D. increases with time

Answer

D

Explanation

`A + B hArr C +D`
`Q=([C])/([A])([D])/([B])`
At the initial states [C] and [D] increases and [A] and [B] decreases. As such at the initial states Q increases.
