During the production of hydrogen iodide, hydrogen reacts with iodine according to the equation:
#H_2(g)+I_2(g)overset(rightarrow)(leftarrow) 2HI(g)#; H=52.0 kJ Explain how the following would affect the yield of hydrogen iodide:
(a) Increase in temperature.
(b) Increase in pressure.

Answer Text:
(a) The yield would increase since H is positive. An increase in temperature shifts the equilibrium to the right.
(b) There is no effect. Volume of the left is the same as on the right.
