For the real gases reaction, `2CO(g)+O_(2)(g)to2CO_(2)(g),DeltaH=-560 kJ.` In 10 litre rigid vessel at 500 K the initial pressure is 70 bar and after the reaction it becomes 40 bar. The change in internal energy is :
A
`-557 kJ`
B
`-530 kJ`
C
`-563 kJ`
D
None of these
Text Solution
Verified by Experts
The correct Answer is:
B
At constant volume `DeltaH = DeltaU + V DeltaP` `implies -560 =DeltaU+10xx(-30)xx0.1` `DeltaU=-530 " kJ"`

For the real gases reaction 2CO(g)+O_(2)(g)rarr2CO_(2)(g) : DeltaH=-560kJ . In a 10 litre rigid vesel at 500K , the initial pressure is 70 bar and after the reaction it becomes 40 bar. The change in internal energy is:
For the reaction 2CO(g) +O_(2)(g) rarr 2CO_(2)(g) , DeltaH=-560 kJ mol^(-1) In 1 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. All the above gases show significant deviation from ideal behavious (1 L atm =0.1 kJ). the change in internal energy will be
In the reaction, CO_(2)(g)=H_(2)(g)toCO(g)=H_(2)O(g)," "DeltaH=2.8 kJ DeltaH represents :
In the reaction CO_(2)(g)+H_(2)(g)rarrCO(g)+H_(2)O(g), DeltaH=2.8 kJ DeltaH represents
For the real gas reaction, 2A(g)+B(g)to2C(g) deltaH=-440kJ//mol If the reaction is carried out in 10 litre rigid vessol, the initial pressure is 50"bar" bar which decreses to 20"bar" in the course of reactioin. The change in internal energy for the reaction is:
For the given real gas reaction, 2A(g)+B(g)rarrD(g) carried out in a 10 liter rigid vesses, the initial pressure is 50 bar which decreases to 20 bar, during the course of reaction. If heat liberated in the reaction is 400 kJ then what is the change in magnitude of internal energy of the reaction (in kJ) ?
