Its temperature dependence is related to the exponential of negative enthalpy in the van't Hoff equation.
This quantity is defined as the product of mole fraction times fugacity coefficient times pressure, raised to the variable nu. The extent of reaction depends on starting concentrations and this quantity. Its temperature dependence is related to the exponential of negative enthalpy in the van't Hoff equation. The change in (*) Gibbs energy in a reaction equals negative RT times the log of this quantity. The law of mass action sets it equal to a ratio of concentrations. By Le Chatelier's principle, a reaction shifts left if Q is greater than this value. For 10 points, name this constant symbolized K which represents a reaction that goes in two directions.
This quantity is defined as the product of mole fraction times fugacity coefficient times pressure, raised to the variable nu.
