General Chemistry II - Exam 2 Questions and Answers | Latest Update | 2024/2025 | 100% Pass How does the concentration of reactants and products influence the position of equilibrium in a chemical reaction? The position of equilibrium shifts to favor the side (reactants or products) where the concentration is decreased or where the concentration is increased, according to Le Chatelier’s principle. What is the reaction quotient (Q), and how is it used to predict the direction o...

For the reaction F2(g) ⇌ 2 F(g), the equilibrium constant at 223 °C is 7.3 x 10-13. If a sample of F2 is heated to 223 °C and allowed to reach equilibrium correct answer: nearly all of F2 will remain unreacted, with a very small amount of F present At equilibrium correct answer: the rate of the forward reaction is equal to the rate of the reverse reaction and the concentration of the reactants and products can be very different For the reaction 2 BrCl(g) ⇌ Br2(g) + Cl2(g), the equi...
