Answer to Question #159935 in General Chemistry for Cybert

Question

Consider the hypothetical reaction: A + 3B → 2C, which gives ΔH0 = 357.2 kJ. Determine the enthalpy of its reverse reaction.

Answer 1

As we know, if we reverse the chemical reaction, then enthalpy change is changed by its sign,

So,

Enthalpy change for reverse reaction = [-357•2] kJ
