Solve this: Q 3 For the reaction, 2CO(g)+O2(g) →2CO2(g) ; ∆H=-560 kJ mol-1 In one litre vessel at 500 - Chemistry -

Question

Solve this:
Q 3 For the reaction,
2 C O ( g ) + O 2 ( g )   → 2 C O 2 ( g )   ;
  ∆ H = - 560   k J   m o l - 1
In one litre vessel at 500 K the initial pressure is 70 atm and
after the reaction it becomes 40 atm at constant volume of one
litre Calculate change in internal energy All the above gases show
significant deviation from ideal behaviour (1 Latm = 0 1 kJ)

IN THIS CASE
WE USE
DELTA H=DELTA U+ DELTA ng RT
-56=DELTA U +(-1*0 0821*500)
WE GET DELTA U=15
