(a) Explain how the following changes would affect the production of hydrogen iodide.
(i) increase in temperature
(ii) decrease in pressure.
(b) Calculate the molar enthalpy for formation of HI (g).

sharon
(a) (i) Increase in temeprature lower the production of HI(g)
Reaction is endothermic
(ii) Decrease pressure had no effect on production HI(g); No. of moles of
gases on both sides equal.
