a) Calculate the Gibbs energy change of the reaction (AG) at 25°C. b) Is the reaction exothermic or endothermic at 25°C? c) A constant volume reactor is initially loaded with an equimolar mixture of A, B and C at 12 bar. The reaction is allowed to take place at constant temperature (T) and when equilibrium is reached, the pressure in the reactor is 15 bar. Unfortunately due to a malfunction in the thermometer, the actual temperature is not known. What is the temperature of the reactor?
