Calculate the enthalpy change for the reaction. Show your work.

A2 + 3B2 --> 2AB3

To calculate the enthalpy change for the reaction, we need to know the enthalpy values for every substance involved, i.e., the enthalpy of formation for A2, B2, and AB3. In general, the enthalpy change for the reaction can be calculated with the formula:

ΔH_reaction = Σ ΔH_products - Σ ΔH_reactants

However, we cannot give a specific solution without the provided enthalpy values for each substance involved in the reaction.
