100 ml of H _ 2( ~g ) and 100 ml of Cl _ 2( ~g ) were allowed to react at 1 bar pressure as H _ 2( ~g ) + Cl _ 2( ~g ) 2 HCl _ ( g ) What will be the PV type of work done diuring reaction?

Step-by-step solution

1 mole of H ₂ reacts with 1 mole of Cl ₂ to produce 2 moles of HCl. Hence, 100 mL of H ₂ would react with 100 mL of Cl ₂ to produce 200 mL of HCl. aligned V ₁ & =100+100=200 ~mL =0.2 dm ^3 ~V ₂ & =200 ~mL =0.2 dm ^3 ~W & =- P _ ext V =- P _ ext ( ~V ₂- V ₁ ) W & =-1(0.2-0.2) & = zero J aligned ( 100 ~J =1 dm ^3 bar ) .
