For the gaseous reaction involving the complete combustion of iso-butane

A

`Delta H = Delta E`

B

`Delta H gt Delta E`

C

`Delta H = Delta E = 0`

D

`Delta H lt Delta E`

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(4)H_(10(g))+(13)/(2)O_(2(g))rarr 4CO_(2(g))+5H_(2)O_((g))`
`Delta n_(g)=+1.5`
`therefore Delta gt Delta E`
