Here's the solution to determine the enthalpy change:

b)
To determine the enthalpy change for the reaction C2H4(g)+H2O(l)→C2H5OH(l)\text{C}_2\text{H}_4(\text{g}) + \text{H}_2\text{O}(\text{l}) \to \text{C}_2\text{H}_5\text{OH}(\text{l}), we will use Hess's Law and the given enthalpy of combustion for ethanol, along with the standard enthalpy of combustion for ethene.

We are given:

  1. $\text{C}_2H_5OH(l) + 3O_2(g) \to 2CO_2(\text
