(A) In a bomb calorimeter,the volume is kept constant.Since $\Delta V = 0$,the work done $w = -P \Delta V = 0$.According to the first law of thermodynamics,$\Delta U = q + w$.Since $w = 0$,$\Delta U = q$.For an exothermic reaction,the heat released $q$ is negative $(q Therefore,$\Delta U < 0$ and $w = 0$.
