(a) What is the ΔƐ value for the oxidation of cytochrome c by the CuA redox center in Complex IV when the ratio of cyt c (Fe2+)/cyt c (Fe3+) is 20 and the ratio of CuA (Cu2+)/CuA (Cu+) is 3?
(b) Calculate ΔG for the reaction in part a. (Express your answer in kJ/mol using three significant figures.)

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
