Question

One mole of a non-ideal gas undergoes a change of state (2.0 atm, 3.0 L. 95 K ) $\rightarrow$ (4.0 atm. 5 0 L, 245 K) with a change in internal energy, $\Delta$E = 30.0L-atm. The change in enthalpy ($\Delta$ H) of the process in L-atm is

• A. 40
• B. 42
• C. 44
• D. not defined, because pressure is not constant

Answer 1

Answer: (C)

44

Answer 2

Work is not a state-function, it depends on path followed.
