Consider the following reactions carried out at a constant temperature and pressure. In which of these will the amount of work done be positive? Hint: only the coefficients of the reactants are given. All species are gas unless otherwise noted.
A) The synthesis reaction of 2 mol SO2 and 1 mol O2 to give SO3.
B) The synthesis reaction of 4 mol NO to give O2 and N2.
C) The decomposition reaction of 2 mol CCl2O to give CO and Cl2. D) The combustion of 2 mol CH3OH.
E) The conversion of 2 mol of solid I2 to gaseous I2.
