WebThe spontaneity of a reaction depends both on the enthalpy change, Delta H, and entropy change. Delta S. Reactions that release energy produce more stable products, and the … WebThe formation ½ A2 + 2 B2 + C --> CAB4 has an enthalpy of formation of -104 kJ and a change in entropy of -60.8 J/K at 30 °C. What is the free energy and spontaneity of the reaction? answer choices
Webwhere Q is the heat that transfers energy during a process, and T is the absolute temperature at which the process takes place.. Q is positive for energy transferred into the system by heat and negative for energy transferred out of the system by heat. In SI, entropy is expressed in units of joules per kelvin (J/K). If temperature changes during … WebFeb 28, 2024 · Re: Spontaneity in reverse direction. I believe that at chemical equilibrium, a system can experience the forward and reverse reactions spontaneously, as neither one side nor the other is favored. By definition, the rates of the forward and reverse reactions are equal during equilibrium, and since both sides would have to be equally favorable ...
