Temperature to enthalpy calculator
WebThis data can be plotted on the temperature/enthalpy curve as illustrated in Figure 2.3.3: ... (Arithmetic mean temperature differences are used to keep this calculation simple; in practice, logarithmic mean temperatures would be used for greater accuracy. Please refer to Module 2.5 ‘Heat Transfer’ for details on arithmetic and logarithmic ... WebWe have constant temperature and pressure. ( μ = Δ G) We can calculate the activities simply over the partial pressures or concentrations. This leads then to your equation: Δ G = Δ G ∘ + R T ln ( Q) where Q is the reaction quotient. Since we assume equilibrium, we know that Δ G = 0 and Q = K. This leads to:
