Assertion : For the combustion of methane, DeltaE gt DeltaH. Reason : DeltaH is related by DeltaE by the expression DeltaH=DeltaE+DeltanRT

Answer»

<P>If both assertion and reason are true and the reason is the CORRECT explanation of the assertion.
If both assertion and reason are true but reason is not the correct explanation of the assertion
If assertion is true but reason is false
If the assertion and reason both are false.

Solution :Combustion of METHANE is
`CH_(4)+2O_(2)rarrCO_(2)+2H_(2)O`The relation between `DeltaH` and `DELTAE` is
`DeltaH=DeltaE+DeltanRT`
`Deltan=n_(p)-n_(r)=1-3=-2`
`DeltaH=DeltaE-2T`
So, `DeltaH lt DeltaE`
Hence, reason is correct explanation of assertion.
