Both questions 3 & 4
Calculate the work done (in joules) by a chemical reaction if the volume increases from 3.2 L to 3.4 L against a constant external pressure of 3.6 atm. What is the sign of the energy change? What is the difference between the internal energy change AE and the enthalpy change AH? Which of the two is measured at constant pressure, and which at constant volume?
