In a balanced chemical equation, if there is no net change in the total number of moles of gas from the reactant side to the product side, then

Quizplus · Accepted Answer

The equilibrium constant expression (K) for a reaction is not directly affected by the stoichiometry of the reaction in terms of the number of moles of gas on each side. It is determined by the concentrations (or partial pressures) of the reactants and products raised to the power of their coefficients in the balanced equation. Therefore, if there is no net change in the total number of moles of gas, it doesn't imply that the equilibrium constant (K) equals 1.00, nor does it imply that the reaction has gone to 50% completion at equilibrium. The statement B) K_p = K_c is a notation error and seems to be a misinterpretation of the equilibrium constant concept. However, interpreting the intent behind the options and the symbols, it seems B is intended to suggest a relationship between different forms of the equilibrium constant (Kp and Kc), which can be related through the ideal gas law, but the notation is incorrect or unclear. Without clear, conventional notation, the explanation relies on standard chemical equilibrium principles, which do not support the given options directly.
