Units for delta H

Postby Riya Sood 4G » Tue Feb 11, 2020 6:04 pm

When is delta H written as KJ/mol and when is it written as KJ?

When the problem asks you to find the heat of phase changes and rising temperatures, you need to consider/mutiply the moles of certain substances. Thus, delta H is KJ or J in this case. When you ask for the reaction enthalpy and the heat(given the heat and the moles), the delta H would be KJ/mole. Based on my observation.
