Question

Glauber's salt, $N{a}_{2}S{O}_4\cdot 10H_{2}O$ , was used by J.R.Glauber in the $17th$ century as a medical agent. At $27^{\circ }C$
${\left(Na\right)}_2{\left(SO\right)}_4\cdot 10H_{2}O\left(s\right)\rightleftharpoons {\left(Na\right)}_2{\left(SO\right)}_4\left(s\right)+10H_{2}O\left(g\right);K_P=4.08\times {\left(10\right)}^{-25}$
Which of the following change will take reaction in forward direction?

• A. Addition more ${\left(Na\right)}_2{\left(SO\right)}_4\left(s\right)$ .
• B. Increase in volume of container.
• C. Addition more water vapors.
• D. Addition $N_2$ gas at constant volume.
