Consider the synthesis of laughing gas, which you might have experienced at the dentist’s office: 2 N2 + O2 ↔ 2 N2O Kc = 2.0 * 10-13 a) Without doing any math, predict whether there will be more products or reactants at equilibrium. Explain your answer. b) If 0.0482 moles of nitrogen and 0.0933 moles of oxygen are introduced into a 1.0L flask, what will be the equilibrium concentrations of each of the three species? c) Without doing any real math – what is the sign of ∆Gº, and how do you know?

22) The ke for the equilibrium shown below is 45. Some methane and hydrogen sulfide are added to a container and at equilibrium the concentrations of methane and hydrogen sulfide are found to be 0.22 mol/L and 0.33 mol/L respectively. What are the equilibrium concentrations of carbon disulfide and hydrogen gas? CH4 + 2H2S(g) → CS2 (g) 4H2
