Which of the following statement is NOT true?     The equilibrium constant of a reaction varies with temperature.     In most biochemical systems, enthalpy is equivalent to heat.     Any deviation from equilibrium prompts a process to restore the system to equilibrium.     Free energy changes can be calculated from reactant and product concentrations.     If a system maintains a steady state it must have reached equilibrium.
