प्रश्न
Answer the following in one or two sentences.
If the enthalpy change of a reaction is ∆H how will you calculate the entropy of surroundings?
उत्तर
If ∆H is the enthalpy change accompanying a reaction (system) the enthalpy change of the surroundings is then –∆H. The entropy change of surroundings can be calculated using the following expression:
`triangle "S"_"surr" = - (triangle"H")/"T"`
