1. Consider the reaction: N2(g)+3H2(g)2NH(g)H2=46,11kJ Predict which of the following changes cause a shift in the oquilibrium towards the fotward direction: (I) Decreasing the temperature of the reaction. (II) Inercasing the volume of the container. (III) Adding more NH3 when the reaction is at equilibrium. (IV) Removing NH3 from the system when the reaction is st equilibrium. a. only (II) b. (I) and (II) c. (II) and (III) d, only (I) c. (I) and (IV) 2. The reaction SbF5(g)+4Cl2(g)SbCl3(g)+5ClF(g) has an equilibrium constant of 0.02 at 300C. Portions of the SbFs (g) and Cl2(g) are mixed at 300C and each have a partial pressure of 0.12atm before the reaction. What is the reaction quotient, Q. before the reaction? a. 0.02 b. 0 c. 1 d. 0.12 e. 2.5105 3. What is the maximum number of grams of PH3 that can be formed when 6.2g of P4 (molar mass: 124g/mol ) reacts with 4.0g of H2 (molar mass: 2g/mol ) to form PH3 (molar mass: 34g/mol) ? P4(g)+6H2(g)4PH3(g)
