3. (5 pts) For a particular reaction, decreasing temperature (at a constant volume) increases the value of K. We can therefore conclude that a) the reaction must be exothermic b) the reaction must be endothermic c) the number of moles of gas must increase in the reaction d) the number of moles of gas must decrease in the reaction e) more than one of these 4. (5 pts) Consider the following reaction: CaCO3 (s) = CaO (s) + CO, (g) At equilibrium at a given temperature, Pc0₂ = 1.5 atm. The volume of the container is then doubled at constant temperature. Which of the following will be true when equilibrium is re-established? Assume the solids occupy negligible volume. a) Pco₂ 1.5 atm b) Pc0₂ < 1.5 atm c) Pco₂ = 1.5 atm
