The enthy change for the reaction of 50 ml of ethylene with 50. 0 ml of ` H_(2)` at 1.5 atm pressure is `DeltaH =- 0.31 KJ `. What is the `DeltaU` ?

Text Solution

Verified by Experts

The correct Answer is:
`-0.3024 kJ`
`C_(2)H_(4)" "+" "H_(2) " " to " "C_(2)H_(6)`
`50 ml " "50ml" "50ml`
`DeltaV = - 50 ml`
`W = - 1.5 (-50) xx 10^(-3) 75 atm - L= 7575 J``DeltaU = q+w`
` = - 0.3024 kJ`
