• # question_answer What is the effect of halving the pressure by doubling the volume on the following system at 500°C   ${{H}_{2(g)}}+{{I}_{2(g)}}$$\rightleftharpoons$ $2H{{I}_{(g)}}$ A) Shift to product side        B) Shift to product formation C) Liquefaction of HI D) No effect

 [d] We know that $PV=nRT$ P become $\frac{1}{2}P$& $V$ bcome $2V$ so, $\frac{1}{2}P\times 2V=PV=nRT$ So there is no effect in equation.
