What is value of PV type of work for following reaction at 1 bar?

Options

  1. A3.5 ~J
  2. B4.5 ~J
  3. C9.0 ~J
  4. D15 ~J

Correct answer

D. 15 ~J

Step-by-step solution

aligned & 1 mole of C ₂ H ₄ reacts with 1 mole of HCl to & produce 1 ~mole of C ₂ H ₅ Cl . & Hence, 150 ~mL of HCl would react with only & 150 ~mL of C ₂ H ₄ to produce 150 ~mL of C ₂ H ₅ Cl . & V ₁=150 ~mL +150 ~mL =300 ~mL =0.3 dm ^3 & ~V ₂=150 ~mL =0.15 dm ^3 & ~W =- P _ ext V =- P _ ext ( V ₂- V ₁ ) & W =-1 bar (0.15 dm ^3-0.3 dm ^3 ) & W =0.15 dm ^3 bar & W=0.15 dm ^3 bar 100 J dm ^3 bar & W=15 ~J aligned The PV work in joules is 15 ~J .
