Question

Consider the following reaction at 298 K:CO(g) + H2O(g) ⇌ CO2(g) + H2(g)Where the initial concentrations of CO and H2O are 0.2 M and 0.1 M, respectively. Calculate the reaction quotient, Qc, for this reaction. Is the reaction at equilibrium or not? If not, in which direction will the reaction tend to proceed to reach equilibrium?

Answer 1

To calculate the reaction quotient, Qc, we need to know the initial concentrations of all the species involved in the reaction. Since we are only given the initial concentrations of CO and H2O, we can assume that the initial concentrations of CO2 and H2 are 0 M.The reaction quotient, Qc, is given by the expression:Qc = [CO2][H2] / [CO][H2O]Using the initial concentrations:Qc =  0  0  /  0.2  0.1  = 0Now, we need to compare Qc with the equilibrium constant, Kc, to determine if the reaction is at equilibrium or not. However, the equilibrium constant, Kc, is not provided in the problem. Without knowing the value of Kc, we cannot definitively determine if the reaction is at equilibrium or predict the direction in which the reaction will proceed to reach equilibrium.If you can provide the value of Kc, we can further analyze the reaction.
