Question

At what temperature must a reaction occur if you are able to calculate the heat of reaction by using standard heats of formation? 50°c 100°c 25°c 0°c

Answer 1

The standard enthalpy of formation is defined as the change in enthalpy when one mole of a substance in the standard state, which is 1 atm of pressure and 298.15 K. 298.15 degrees K is equal to 25 degrees Celsius, so 25 C is your answer.
