Consider the reaction of CrCl_2 with H_2 to form solid Cr At T = 632 Celsius , K = 1.98*10^(-5) , At T = 806 Celsius , K = 1.12*10^(-3) . Answer the following questions:

(a) From these data, estimate the enthalpy of reaction.

(b) In an attempt to increase the extent of reaction, the reaction temperature is raised to 1000 Celsius and 1 bar At equilibrium, how much Cr is produced for every mole of H_2 in the feed?

(c) Additionally, you wish to increase the extent of reaction by changing the pressure. Would you increase or decrease the pressure? Explain.
