Question

A system at equilibrium is described by the equation of fixed temperature $T$.
$S{O}_{2}C{l}_2\left(g\right)\rightleftharpoons S{O}_2\left(g\right)+C{l}_2\left(g\right)$
What effect will an increase in the total pressure caused by a decrease in volume, have on the equilibrium?

• A. Concentration of $S{O}_{2}C{l}_2\left(g\right)$ increases
• B. Concentration of $S{O}_2\left(g\right)$ increases
• C. Concentration of $C{l}_2\left(g\right)$ increases
• D. Concentration of all gases increases

Answer 1

The correct option is D Concentration of all gases increases

Concentration of all gases increases and equilibrium shifts towards lesser number of moles but new equilibrium concentration of every gas would be higher than earlier.
