CHEM 112Winter 2021Week 2 Recitation ProblemsQuestion 1(a)Continuing with the discussion of water-gas shift reaction in last week’s recitation problem:CO(g) + H2O(g)CO2(g) + H2(g)Industrial reactors often utilize higher temperature (e.g.T= 800 K) and higher pressure (80atm) to increase the reaction rate. Does higher temperature also improve the efficiency of thereaction? Why or why not? What about higher pressure? For the purpose of this question, theefficiency is defined by the percentage of H2O converted to H2. You may use calculations tojustify your answer, although it is not completely necessary.
(b)Limestone (calcium carbonate) is commonly used in the industrial production of quicklime(calcium oxide) via the following reaction:CaCO3(s)CaO(s) + CO2(g)The reaction is endothermic. For each of the changes below, identify how it will shift theequilibrium and impact the free energy change
