1. What effect would the changes below have on this equilbrium? 2SO2(g)+O2(g)2SO3(g)+heat a) [SO2] is increased. w. [SO3] is decreased. a) Temperature is increased. a) Volume of container is increased. a He is added at constant volume. 2. Write the equilibrium expression for the reaction in question 1. 2.A(g)+B(g)AB(g)K=4.0102 0.50 mol of A and 0.60mol of B were placed in a 2.0 L container. Calculate the concentration of AB at equilibrium. 4. At 773C, a mixture of CO(9),H2(g) and CH2OH was allowed to come to equilibtium. The following equilibrium concentrations were then measured: [CO]=0.105M,[H2]=0.250M,[CH2OH]=0.00261M. Calculate K for the reaction CO(g)+2H2(g)/CH3OH (g) 5. Al a high temperature. 0.500 mol HBr was placed in a 1.00L container and allowed to decompose according to the reaction 2HBr(g)H2(g)+Br2(g) At equilibrium, the concentration of Br was measured to be 0.130M. What is the K for the reaction? At a certain temperature, the reaction CO(g)+H2O(g)CO2(g)+H2(g) has K=0.400. Exactly 1.00 mol of each reactant was placed in a 100L vessel and the mixture was allowed to react. What were the equilibrium concentrations of each gas? 7. Write the K expression for the dissolving of each of the following in water: a) Siver chromate b) Calcium phosphate 4. Calculate the molar solubility, in moles per litre, of calcium sulphate. Kw=2.4105. " Calculate the pH of a 0.050M solubion of sodium hydroxide, a strong base. 12. Calculate the [HO] for 0.50M solution of acetic acid. Ka= 1.8105 ii.
