What is the rate expression for the production of X, which is a gas, at constant volume? A) rate = P_gVΔ[X]/RΔt B) rate = -TΔ[X]/P_gVΔt C) rate = -P_gV(Δ[X]/TΔt) D) rate = (1/RT)(ΔP_X/Δt) E) rate = (1/RΔP_X)(VT/Δt)

For the production of a gas at constant volume, the rate expression is given by the ideal gas law: PV = nRT Rearranging for the production of X, we get: VΔ[X] = (Δn)RT = (ΔP_X)RT Dividing both sides by RTΔt, we get: (ΔP_X/Δt) / RT = rate of production of X Therefore, the rate expression is given by choice D, which is (1/RT)(ΔP_X/Δt).
