Calculate the PV type of work for the following reaction at 1 bar pressure. (150 ~mL ) C ₃ H _ 6( ~g ) + (150 ~mL ) HCl _ ( g ) (150 ~mL ) C ₃ H ₇ Cl _ ( g )

Options

  1. A5.2 J
  2. B10.21 J
  3. C15.00 J
  4. D18.2 J

Correct answer

C. 15.00 J

Step-by-step solution

aligned W & =- P _ ext V =- P _ ext ( V ₂- V ₁ ) V ₁ & =150+150=300 ~mL =0.3 dm ^3 ~V ₂ & =150 ~mL =0.15 dm ^3 P _ ext & =1 bar W & =-1(0.15-0.3) & =0.15 dm ^3 bar & =15.0 ~J ( 100 ~J =1 dm ^3 bar ) aligned
