(1) What is the expansion work done by the system?
First, the equation for the burning of carbon should be established.
The expansion work is defined as the product of the change in volume and the pressure. Under standard temperature and pressure, one mole of gas occupies 22.4L of volume. The left side of equation (8) contains one mole of gas, while the right side contains only one. In comparison, the change in the volume of the solid is insignificant. The expansion work is therefore given by
