Calculate the reaction enthalpy, ΔH, for the following reaction:     CH4(g)+2O2(g)→CO2(g)+2H2O(l) Use the series of reactions that follow:

1. C(s)+2H2(g)→CH4(g), ΔH =−74.8 kJ.
2. C(s)+O2(g)→CO2(g), ΔH =−393.5 kJ.
3. 2H2(g)+O2(g)→2H2O(g), ΔH =−484.0 kJ.
4. H2O(l)→H2O(g), ΔH =44.0 kJ.

Step 1

As per the question, given reactions are mentioned below:

Step 2

The reaction for which enthalpy is to be calculated will get by first adding equation (2) and (3) then subtracting equation (1) and (4) from the added result, by first multiply equation (4) by 2.  On doing so, the result will be shown as follows:

Step 3

The above result is the reaction for which enthalpy is to be determined.
