What is the value of internal energy change `(Delta U) at 27^(@)C` of a gaseous reaction:`2 A _(2 (g))+ 5 B _(2) (g) to 2 A _(2) B _(5) (g)` (whose heat change at constant pressure is–50700J)? `(R = 8.314JK^(-1)mol^(-1))`

A

`-50700J`

B

`-63171J`

C

`-38229 J`

D

`+38229 J`

Text Solution

Verified by Experts

`Delta H = Delta U + Delta n _(g) RT , - 50 700 = Delta U + (-5) xx 8. 314 xx 300 , Delta U =-38229 J`
