Final answer:
The equilibrium constant (K) for H2(g) + CO2(g) → H2O(g) + CO(g) cannot be calculated without all the equilibrium concentrations. Option B is correct.
Step-by-step explanation:
The equilibrium constant (K) is a value that reflects the ratio of the concentrations of the products to the reactants at equilibrium. To determine the value of K for the reaction H2(g) + CO2(g) → H2O(g) + CO(g), we need the equilibrium concentrations of all the substances.
This question, however, does not provide all equilibrium concentrations, so we cannot calculate K with the information given. Instead, we must refer to other data or experimental results to determine K at a specific temperature. For example, with data given at a different temperature (700 K), we could apply the equation K = [H2O][CO] / [H2][CO2] to find the equilibrium constant if the equilibrium concentrations were known.
To determine the value of the equilibrium constant, we need to use the given information. However, the given information does not include the value of the equilibrium constant at 600 K. Therefore, we cannot calculate the value of the equilibrium constant for the reaction H2(g)+CO2(g)→H2O(g)+CO(g) at 600 K.
