Question

If a chemical reaction is carried out in four steps and the same reaction can be

Answer 1

Answer - b) Be the same as in the second method

Brief explanation:

Enthalpy is an state function that does not depend on the path followed to carry out the reaction but depends upon the initial and final state of system. In above statement both the reaction are same hence the enthalpy change would also be same. This can also be represent in the form of equation,

ΔHsys = Hf - Hi

Where,

• ΔHsys is change in enthalpy of system
• Hf is enthalpy of reaction at final state
• Hi is enthalpy of reaction at initial state
