Your explosive reaction should have resulted in a negative enthalpy change, which is indicative of an exothermic reaction. Remembering the definition of "exothermic", write a sentence or two on how this "exothemicity" may affect the value for the volume of gas you used to calculate expansion work. There are 2 steps to solve this one.
