72 Hebden : Chemistry 12 61. The equilibrium constant for the reaction N2(g) +3 H2(g) 2 NH3(g) is 3.0 at a certain temperature. Enough NH3(g) was added to a 5.0 L container such that at equilibrium the container was found to contain 2.5 mol of N2(g). How many moles of NH3(g) were put into the container? 62. Keg = 1.00 for N2O2(g)+H 2(g) N20(g)+ H20(g). If 0. 150 mol of N20(g) and 0.250 mol of H20(g) were introduced into a 1.00 L bulb and allowed to come to equilibrium, what concentration of Na02(g) %3D was present at equilibrium? 63. A reaction mixture at equilibrium, H2(g)+12(g) 2 HI(g), contains 0.150 mol of H2(g), 0.150 mol of b(g) and 0.870 mol of HI(g) in a 10.0 L vessel. If 0.400 mol of HI(g) is added to this system and the system is allowed to come to equilibrium again, what will be the new concentrations of H2, 12and HI? 64. A reaction mixture, 2 NO(g) +O2(g) 2 NO2(g), contained 0.240 mol of NO(g), 0.0860 mol of O2(g) and 1.20 mol of NO2(g) when at equilibrium in a 2.00 L bulb. How many moles of O2(g) had to be added to the mixture to increase the number of moles of NO2(g) to 1.28 when equilibrium was re-established? 65. A reaction mixture, 2 ICI(g) + H2(g) 12(g) + 2 HCI(g), was found to contain 0.500 mol of ICI(g). 0.0560 mol of H2(g), 1.360 mol of I2(g) and 0.800 mol of HCI(g) at equilibrium in a 1.00 L bulb. How many moles of ICI(g) would have to be removed in order to reduce the [HCI(g)] to 0.680 M wher equilibrium is re-established?
