Calculate change in internal energy if D...

Calculate change in internal energy if `Delta H= - 92.2 kJ, P = 40` atm and `Delta V = - 11`.

A

`- 42 kJ`

B

`-88 kJ`

C

`+88 kJ`

D

`+42 kJ`

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta H = Delta E+P Delta V`
`Delta E = Delta H-P Delta V = - 92.2-40xx(-1)xx101xx10^(-3)`
`=-92.2+4.04=-88.16 kJ ~~ -88 kJ`.
