**Question 3 of 15**Identify the relationship between ΔH and ΔE (or ΔU) for a reaction in which ΔV is negative at a constant pressure.- ☐ ΔH < ΔE- ☐ ΔH = ΔE- ☐ ΔH > ΔE---**Explanation:**This question asks you to determine how the enthalpy change (ΔH) compares to the change in internal energy (ΔE or ΔU) for a reaction where the volume change (ΔV) is negative and pressure is constant. For a reaction under constant pressure, the relationship between ΔH and ΔE is given by:\[ \Delta H = \Delta E + P\Delta V \]When ΔV is negative, this means volume is decreasing, which suggests that ΔH might be less than ΔE. Your task is to select the correct relationship from the provided options:- ΔH is less than ΔE- ΔH is equal to ΔE- ΔH is greater than ΔE

According to the first law of thermodynamics, the internal energy change and enthalpy change of a process are related as follows: ∆H=∆E+P∆V where, ∆H = change in enthalpy ∆E = change in internal energy P∆V = pressure-volume workThe pressure-volume work done on the system or done by the system depends on the pressure and change in volume. If the change in volume is zero then the work done on the system or done by the system will be zero and the internal energy change and enthalpy change of the thermodynamic process will be the same.For the given process the change in volume is negative at constant pressure, hence the internal energy change and enthalpy change of the process are given by: ∆H = ∆E + P-∆V∆H = ∆E - P∆V∆H + P∆V = ∆EHence we can say that:∆H > ∆EThe right option is as follows: ∆H > ∆E
