ΔH

Postby Noh_Jasmine_1J » Thu Feb 07, 2019 12:12 pm

I thought when we calculated for ΔH, the equation used was ΔH=nCΔT, but in some calculations they don't use ΔT. Why is that?

There are different ways to calculate the enthalpy change. For example, you can use bond energy and standard enthalpy of formation. They do not require the equation that you showed.

ΔH represents the change in energy, so there are different equations based on the information you are provided in the problem (ie. bond enthalpy, enthalpy of vaporization, calorimetry, etc.)
