could someone help with 113 - 118?
Consider the Haber process after equilibrium is reached. Which of the following changes to the system would cause the reaction to "shift" towards the reactants in the forward direction? adding more nitrogen gas to the system removing ammonia gas from the system adding more hydrogen gas to the system removing nitrogen gas from the system adding ammonia gas to the system more than one of the choices above would cause the desired "shift" The hypothetical reaction AB + CD AC + BD is allowed to reach equilibrium at room temperature. At equilibrium, the concentrations of AB and CD are found to be [0.90] and [1.12], respectively. When the reaction is carried out at 50 degrees C, the equilibrium concentrations of AB and CD are found to be [0.78] and [0.60], respectively. Is the reaction endothermic or exothermic? PLACE ANSWER HERE Any proton acceptor would be classified as an Arrhenius base TRUE FALSE The strength of acids is determined by their volatility (i.e., their boiling points) TRUE FALSE List three major reasons why the Bronsted-Lowry theory is a more complete acid base theory than the Arrhenius theory for applications to living systems.

Answer – 109) We know the Haber process reaction
N2(g) + 3H2(g) <----> NH3(g)
So for the equilibrium shift towards the reactant side with forward direction we need to added more NH3(g) or remove the reactant like N2(g) or H2(g), so the equilibrium will shift towards the reactant side. So we are given two option d and e are cause the equilibrium shift towards the reactant side, so correct answer for this one is option number f.
110) We are given the at room temp the equilibrium concentration of AB and CD found 0.90 and 1.12 M respectively. When we carry out this reaction at 50o C, means at more temp then the equilibrium concentration of AB and CD found 0.78 and 0.6 M respectively. So as we carry out the reaction at higher temp then there is more reactant gets converted to product, since at equilibrium there is remaining less concentration of AB and CD, we know when reaction goes spontaneous at higher temp that means it is endothermic process. So this reaction is endothermic reaction.
111) We know Arrhenius base are the OH- donor in the aqueous solution, so any proton acceptor would be classified as an Arrhenius base is false.
112) The strength of acid is determined on the how it is easily donating the proto and not on the its boiling point, so this one is false.
