Why does the reaction quotient (Q) increase with time as the reaction proceeds to equilibrium?

6 years ago


Answers : (1)

										let a reaction A + B == C + D

the value of Q = [C][D]/[A][B].

Initially the concentration of C and D is zero and the concentrations are only of A and B.

More concentration of a compound will give more probability to react with another substance. Initially the concentrations of A and B are high, so more chance to interact with each others. more chance to form the compounds C and D. So A and B will convert into C and D. The concentration of A and B will go down and rate of change from A+B to C+D will go down.

so in Q equation [A] and [B] decreasing and [C] & [D] increasing.

So Q value will increases with time as the reaction proceeds to equilibrium.
