Question

Difference between deltaHand deltaE for the confusion of liquid benzene at 27degreeC

Answer 1

Answer:

Solution :

We know ΔH=ΔEΔngRT

or ΔH−ΔE=ΔngRT

Delta H and Delta E is same for combustion of methane hence the difference is 0

CH4+2O2=CO2+2H2O

Here Δng=18−17=1

So, ΔH−ΔE=1×8.31J/k/mol×300K=2493J/mol
