The dealership wants to see you every three months.â. But he acknowledged that â3,000 miles strikes a deep chord with the consumer,â adding: âIt feels good to get an oil change. If you fill up the car with gas, wash it and change the oil, it runs better.
Since this measurement is at constant pressure (isobaric), the heat is equal to the change in enthalpy or \(\Delta H\). Note: be careful with the sign on \(\Delta H\). Heat out of the reaction is heat in to the calorimeter and vice versa.ince this measurement is at constant pressure (isobaric), the heat is equal to the change in enthalpy or \(\Delta H\).

When a system is at equilibrium where no net change occurs, then delta G is zero. The delta G of a reaction is the free energy of the final state minus the free energy of the initial state, making it is independent of the reaction pathway.However, the value of delta G provides no information on the rate of a reaction.he delta G of a reaction is the free energy of the final state minus the free energy of the initial state, making it is independent of the reaction pathway.
