In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions that are thermodynamically favorable. as long as the overall reaction is thermodynamically favorable, even the unfavorable reaction will proceed.
part a: consider these hypothetical chemical reactions:
a⇌b,δg= 11.9 kj/mol
b⇌c,δg= -26.7 kj/mol
c⇌d,δg= 7.30 kj/mol
what is the free energy, δg, for the overall reaction, a⇌d?

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
