Calculate change in internal energy if ( H=-92.2 ~kJ , P=40 ~atm ) and ( V=-1 ~L ).

Options

  1. A(-42 ~kJ )
  2. B(-88 ~kJ )
  3. C(+88 ~kJ )
  4. D(+42 ~kJ ).

Correct answer

B. (-88 ~kJ )

Step-by-step solution

( H= E+P V ) ( aligned E & = H-P V=-92.2-40 (-1) 101 10⁻³ & =-92.2+4.04=-88.16 ~kJ -88 ~kJ . aligned )
