CO ના મોલ $fraction numerator 9.55 over denominator 28 end fraction space equals space 3.234$
CO₂ ના મોલ $equals space fraction numerator 9.45 over denominator 44 end fraction space equals space 0.215$

$straight P subscript CO space equals space straight X subscript CO times straight P subscript ક ુ લ space end subscript space space space space space space space space space space space space space space space space space space space space space space space space space straight X subscript CO space equals space fraction numerator 3.234 over denominator 3.234 space plus space 0.215 end fraction space space space space space space space space equals space 0.938 space cross times space 1 space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 0. space 938 space space space space space space space space equals space 0.938 space વ ા ત ા વરણ$

$straight P subscript CO subscript 2 end subscript space equals space straight X subscript CO subscript 2 end subscript space times space straight P subscript ક ુ લ space space space space space space space space space space space space space space straight X subscript CO subscript 2 end subscript space equals space 1 space minus space 0.938 space space space space space space space space space space space space equals space space 0.62 space cross times space 1 space space space space space space space space space space space space space space space space space space space space space space space space space equals space 0.062 space space space space space space space space space space space space equals space 0.062 space વ ા ત ા.$

$therefore space space straight K subscript straight p space equals space fraction numerator straight P squared co over denominator Pco subscript 2 end fraction$ મેળવવું

તથા $straight K subscript straight p space equals space straight K subscript straight C left parenthesis RT right parenthesis to the power of increment straight n left parenthesis straight g right parenthesis end exponent$ પરથી K_C મેળવવું.

$therefore space space straight K subscript straight p space equals space fraction numerator straight P squared co over denominator Pco subscript 2 end fraction$ મેળવવું
