The question seems to be incomplete as it does not provide enough information to calculate the work done during the reaction. In thermodynamics, work done on or by the system is calculated using the formula w = -PΔV, where P is the pressure and ΔV is the change in volume. Without these values, it's impossible to calculate the work done.

However, if we consider the reaction at constant pressure and volume (which is a common assumption), then no work is done on or by the system because the volume doesn't change.

In terms of whether the work is done on or by the system, it depends on the sign of the work. If the work is positive, it is done by the system on the surroundings. If the work is negative, it is done on the system by the surroundings.

Again, without specific values or conditions given in the problem, it's impossible to give a definitive answer.

Consider the explosion of a hydrogen balloon. 2H2(g) + O2(g) ⟶ 2H2O(g) How much work is done and is it on or by the system? - 7.5 kJ -2.5 kJ 7.5 kJ +2.5 kJ
