What happens when a system has reached chemical equilibrium? The concentration of reactants has reached zero false The concentration of products has become asymptotic false The concentration of products has reached its maximum false The concentrations of the reactants and products no longer change true Single The Law of Mass Action is valid: Only for reversible reactions at equilibrium true Only for irreversible reactions at equilibrium false For both reversible and irreversible reactions false For any type of reaction regardless of equilibrium state false Single From what country did Cato Guldberg and Peter Waage come from? Norway true Sweden false Germany false Russia false Single Suppose you have a reversible reaction at equilibrium. What does it mean when its equilibrium constant is equal to 5? The products are five times more concentrated than the reactants false The reactants are five times more concentrated than the products false The products have a higher concentration than the reactants true The reactants have a higher concentration than the products false Single Suppose the reactant of a reversible reaction has a stoichiometric coefficient of 5 while that of its product has 3. What would be the equation that will relate this reaction's Kp with its Kc? K_p = K_c(RT)₂ true K_p = K_c(RT)₃ false K_p = K_c(RT)₅ false K_p = K_c(RT)₈ false Single In the reversible reaction R + S ⇌ E + F, R and S are in the gaseous phase, E is dissolved in an aqueous solution, and F is a solid. Among these species, whose concentration(s) should appear in the reaction's Kc expression? R and S only false E and F only false R, S, and E only true R, S, E, and F false Single The Kc of a certain forward reaction is 4. What would be the Kc of its reverse reaction? -4 false -0.25 false 0.25 true 4 false Single A key difference between the equilibrium constant Kc and the reaction quotient Qc is that: Only non-equilibrium concentrations are used to find Qc true Only equilibrium concentrations are used to find Qc false Any concentration, regardless of equilibrium state, can be used to find Qc false Qc is not temperature- dependent false Single Under which of the following conditions is the reverse reaction of a system favored? Q_c = -∞ false Q_c < K_c false Q_c > K_c true Q_c = ∞ false Single The progression, rate, and yield of a real-world reversible reaction is affected by the concentration of reactants and products that can actually participate. What is this concentration called? differentiation false disequilibrium false deviation false activities true Single
