Question

22. Calculate the enthalpy of combustion of ethylene<br />at 1 atm pressure and 298 K, if enthalpy of<br />formation of CO2(g), H2O(l) and C2H4(g) are -394,-242 and -52 kj <br />respectively​

Answer 1

Answer:

Explanation:

The first thing to do here is write a balanced chemical equation .

SInce the standard enthalpy change of reaction,

, for this reaction was not provided, you're going to have to calculate it using standard enthalpies of formation

The standard enthalpy change of reaction can be calculated by using the equation.

- the number of moles of each product and reactant, respectively
