Calculate the PV type of work for the following reaction at 1 bar pressure. C_3H_ 6(g) + HCl_ (g) C_3H_7Cl_ (g) (150 mL) (150mL) (150 mL)

MHT CET 2023 Chemistry question

Calculate the PV type of work for the following reaction at 1 bar pressure. + (150 mL) (150mL) (150 mL)

(A)5.2 J
(B)10.21 J
(C)15.00 JCorrect
(D)18.2 J

Answer: (C)

Solution

Work of expansion/compression at constant external pressure is (IUPAC sign: positive when work is done on the system). The initial volume of the gases is mL and the final volume is 150 mL, so . $w = -(1\
