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 \(\Delta H\).

k<1. delta Go is the standard-state free energy. When this is negative, the reaction is spontaneous, therefore k is greater than one because more product is produced. When delta Go is positive, the reaction is not spontaneous because it requires the input of energy at standard conditions. K is therefore less than one because the reaction favors the reactants.
