Question

What are the factors affecting the ∆E and ∆H?☺

Answer 1

Hi there,

Factors affecting ∆H

1. The Physical form of Reactants and Products: The Change in Physical State changes the Enthalpy of the Reaction.

2. Temperature and Pressure: Temperature and Pressure Greatly influence the Enthalpy of Reaction.

3. Amount of Reactants: The Change in Enthalpy is Reactant dependent.

Factors affecting ∆E

1. Temperature: Temperature is directly proportional to the internal Energy of a System.

2. Pressure: Constant pressure with Temperature can increase internal Energy.

3. Physical State: The increase in Volume after getting Convert from Solid to Liquid increases the potential energy of the Molecules.

Hope it helped.
