Chemical and Ionic Equilibrium 1 Question 19

20. 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

(2000)

(a) is zero

(b) decreases with time

(c) is independent of time

(d) increases with time

Show Answer

Solution:

  1. A+BC+D,Q=[C][D][A][B]

As time passes, amount of products ’ C ’ and ’ D ’ increases, hence Q increases.
