1) Describe the different ways to shift the equilibrium to the left for the following reaction:
2 A (s) + 2 BC (aq) –> 2 AB (aq) + C2(g).
Justify your answer.
?H = -352 kJ
2) A classmate asks for your help writing an equilibrium expression for the combustion of methane gas: CH4(g) + 2 O2(g) –> CO2(g) + 2 H2O(l). Explain to her why it is not meaningful to create an equilibrium expression or calculate an equilibrium constant for this reaction.
