- For the equilibrium reaction in Question 4, write the expression for the equilibrium constant. (a) How would this equilibrium constant change if the total pressure on the system were doubled? (b) How would the equilibrium constant change if the temperature were increased?arrow_forwardWrite a balanced chemical equation for a totally gaseous equilibrium system that would lead to the following equilibrium constant expression. Keq=[N2]2[H2O]6[NH3]4[O2]3arrow_forward. Explain what it means that a reaction has reached a state of chemical equilibrium. Explain why equilibrium is a dynamic state: Does a reaction really “stop” when the system reaches a state of equilibrium? Explain why, once a chemical system has reached equilibrium, the concentrations of all reactants remain constant with time. Why does this constancy of concentration not contradict our picture of equilibrium as being dynamic? What happens to the rates of the forward and reverse reactions as a system proceeds to equilibrium from a starting point where only reactants are present?arrow_forward
- For the reaction C6H6(g)+3H2(g)C6H12(g)+heat determine in what direction the equilibrium will be shifted by each of the following changes. Decreasing the concentration of H2 a. Increasing the concentration of C6H6 b. Decreasing the temperature c. Increasing the pressure by decreasing the volume of the containerarrow_forwardWrite equilibrium constant expressions for the following generalized reactions. a. 3X(g)+2Y(g)Z(g) b. 3X(g)+2Y(s)Z(g) c. 3X(s)+2Y(s)Z(g) d. 3X(g)+2Y(g)Z(s)arrow_forwardExplain that equilibrium is dynamic, and that at equilibrium the forward and backward reaction rates are equal.arrow_forward
- Write an equation for an equilibrium system that would lead to the following expressions (ac) for K. (a) K=(Pco)2 (PH2)5(PC2H6)(PH2O)2 (b) K=(PNH3)4 (PO2)5(PNO)4 (PH2O)6 (c) K=[ ClO3 ]2 [ Mn2+ ]2(Pcl2)[ MNO4 ]2 [ H+ ]4 ; liquid water is a productarrow_forwardThe value of the equilibrium constant, K, is dependent on which of the following? (There may be more than one answer.) a. the initial concentrations of the reactants b. the initial concentrations of the products c. the temperature of the system d. the nature of the reactants and products Explain.arrow_forward
