Question

55 L atm of work is obtained when 1.0 mole of an ideal gas is compressed isothermally from
a volume of 28.5 L to 18.5 L, the constant external pressure is

(A) 5.05 atm

(B) 5.5 atm

(C) 0.05 atm

(D) 0.55 atm

Solution

 

(B) 5.5 atm [1]
`W = – P_(ex).DeltaV`
`55 = - P_(ex)(18.5 – 28.5)`
`- Pex = -55/10=5.5 atm`

  Is there an error in this question or solution?
