Question

Which of the following is a direct application of Hess's Law?
Options
A Predicting boiling point
B Calculating enthalpy change of complex reactions
Correct Answer
C Determining rate of reaction
D Measuring bond angles
Correct Answer

Option B is the correct answer.

Detailed Explanation

Hess's Law is used to calculate the enthalpy change for reactions that are difficult to measure directly. By using known enthalpy changes for other reactions, the target ΔH can be found through algebraic summation.

Hint

This law allows us to find ΔH for a reaction by combining the ΔH values of other reactions.
