Answer the following in one or two sentences. If the enthalpy change of a reaction is ∆H how will you calculate entropy of surroundings? - Chemistry

Short Note

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?

Solution

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"

Is there an error in this question or solution?
