... It is difficult to measure directly. However, two other reactions are known: C(graphite) + O2(g) CO2(g); DH = -393.5 kJ 2CO2(g) 2CO(g) + O2(g); DH = – 566.0 kJ In order for these to add to give the reaction we want, we must multiply the first reaction by 2. Note that we also multiply DH by 2. ...

... Rearranging gives x = [I2(g)] = 0.0139 M. Answer: 0.0139 M If 0.274 g of H2S were now introduced into the same flask, what would be the concentration of S2(g) at equilibrium? The molar mass of H2S is (2 × 1.008 (H) + 32.06 (S)) = 34.08 g mol-1. Hence, 0.274 g of H2S corresponds to: number of moles = ...
