Chapter 11, Problem 117E

Interpretation Introduction

Interpretation:

‘Percentage of CO conversion need to be calculated, if the pressure in 2.45 L flask dropped to 552 torr from 745 torr in a chemical reaction having mole ratio 2:1‘ should be identified.

Concept introduction:

percentage of CO conversion can be calculated by subtracting the respective Pressure of reactants from the final pressure and multiplying by 100 to get the percentage as follows:

$\frac{{\mathrm{P}}_{\mathrm{f}}-{\mathrm{P}}_2}{{\mathrm{P}}_{\mathrm{f}}-{\mathrm{P}}_1}\times 100$

Given:

P_f is the final pressure = 745 torr

n_{1 is initial mole of CO= 2}

n₂ is final mole = 2+1 =3
