For the reaction, 2 HI (g) H ₂(g)+ I ₂(g) ;-Q ~kJ , the equilibrium constant depends upon

Step-by-step solution

For the following reaction, aligned &2 HI (g) H ₂(g)+ I ₂(g) ;-Q ~kJ & n= (n_ P )_ g - (n_ R )_ g =(1+1)-2=0 aligned Equilibrium constant (K_ C ) is independent of pressure and volume. Heat is given in the reaction ( H=+ ve) According to Le-Chatelier's principle, on increasing temperature equilibrium shifts towards left hence, K_ C decreases. Catalyst only speeds up the reaction i.e., it help to achieves equilibrium faster without effecting the equilibrium point.
