JEE Main20204 Sep 2020Evening ShiftChemistryChemical EquilibriumActual
If the equilibrium constant for A ⇌ B + C is K eq ( 1 ) and that of B + C ⇌ P is K eq ( 2 ) , the equilibrium constant for A ⇌ P is :
Options
- AK eq ( 1 ) / K eq ( 2 )
- BK eq ( 2 ) - K eq ( 1 )
- CK eq ( 1 ) + K eq ( 2 )
- DK eq ( 1 ) K eq ( 2 )
Correct answer
D. K eq ( 1 ) K eq ( 2 )
Step-by-step solution
On adding Reaction 1 st and Reaction 2 nd we get. A ⇌ P    K eq = K eq ( 1 ) · K eq   ( 2 )
