For the reaction
\(C H_{3} C O O H \left(\right. l \left.\right)+ 2 O_{2} \left(\right. g \left.\right) \)
\(\rightleftharpoons 2 C O_{2} \left(\right. g \left.\right)+ 2 H_{2} O \left(\right. l \left.\right)\)
at 25°C and 1 atm. pressure, ΔH = –874 kJ. The change in internal energy (ΔE) is:
1. – 874 kJ
2. – 971.53 kJ
3. + 971.53 kJ
4. + 874 kJ
The maximum work done in expanding 16g isothermally at 300 K and occupying a volume of
5 dm3 until the volume becomes 25 dm3 is:
1. –2.01 J
2. 2.01× J
3. +2.81 J
4. +2.01J
