Solution 1

The Hreaction (enthalpy change) in J/mol can be calculated by dividing the total energy used by the number of moles.

In this case, the total energy used is 24 J and the number of moles is 3.

So, the Hreaction = 24 J / 3 moles = 8 J/mol.

Therefore, the answer is B. 8 J/mol. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study problem. Knowee AI St
