Chemical and Ionic Equilibrium - Result Question 20
####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:
- $A+B \rightleftharpoons C+D, Q=\frac{[C][D]}{[A][B]}$
As time passes, amount of products ’ $C$ ’ and ’ $D$ ’ increases, hence $Q$ increases.
