Chemistry - Chemical Equilibrium Question with Solution | TestHub

${\mathrm{K}}_{\mathrm{c}}=\frac{{\left[{\mathrm{SO}}_3\right]}^2}{{\left[{\mathrm{SO}}_2\right]}^2\left[{\mathrm{O}}_2\right]}$ If volume is reduced to half, ${\mathrm{K}}_{\mathrm{c}}$ will decrease to half. Thus, to maintain the equilibrium, the reaction should shift in the forward direction, i.e. towards right. Also, to attain equilibrium back, the rate of forward direction will become double the rate of backward direction.
