Why is the concept of enthalpy useful in chemical reactions?

Options

  1. AEnthalpy is a state function, making calculations simpler.
  2. BEnthalpy is a measure of temperature changes.
  3. CEnthalpy is directly proportional to the volume change.
  4. DEnthalpy is unrelated to chemical reactions.

Correct answer

A. Enthalpy is a state function, making calculations simpler.

Step-by-step solution

Enthalpy is a state function, meaning it depends only on the initial and final states of the system, making calculations more straightforward as the path taken doesn't matter.
