WebJan 30, 2024 · How the Gas Equilibrium Constants Relate to Reaction Quotient (Q) The process of finding the Reaction Quotient (Q c) is the same as finding K c and K p, where the products of the reaction is divided by the reactants of the reaction ( Products Reactants) at any time not necessarily at equilibrium. WebQ = mc∆T. Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) What is Q for an ideal gas? Q = nCVΔT. For an ideal gas, applying the First Law of Thermodynamics tells us that heat is also equal to: Q = ΔEint + W, although W = 0 at constant volume. How do you find Q without C?

WebEsys = q (if and only if w = 0) The easiest way to achieve these conditions is to run the reaction at constant volume, where no work of expansion is possible. At constant volume, the heat given off or absorbed by the reaction is equal to the change in the internal energy that occurs during the reaction. Esys = qv (at constant volume)
