Answer to Question #279965 in Inorganic Chemistry for Rea

Question

What effect do the listed changes have. On the position of the equilibrium in the reaction of carbon with hydrogen?

C (s) + 2 H2(g) = CH4(g) ∆H= -18 kcal/ mol

A. Increasing temperature

B. Increasing pressure by decreasing volume

C. Allowing CH4 to escape continuously from the reaction vessel

Answer 1

Increasing the temperature decreases the value of the equilibrium constant. Where the forward reaction is endothermic, increasing the temperature increases the value of the equilibrium constant. ... If you increase the temperature, the position of equilibrium will move in such a way as to reduce the temperature again.
