... 1. In the reaction 2 H2(g) + O2(g) → 2 H2O(l), 3 mol of gas-phase molecules is replaced by 2 mol of liquid-phase molecules, so ∆ng = −3 mol. Therefore, at 298 K, when RT = 2.5 kJ mol−1, the enthalpy and internal energy changes taking place in the system are related by • Note that the difference is e ...

... The internal energy (E) of a system is the sum of KE and PE of all particles in the system. The internal energy of a system can be changed by a flow of work, heat, or both. i.e. ΔE = q + w ΔE: change of E, q: heat, w: work Thermodynamic quantities always consist of two parts: a number, giving the ma ...
