Equilibrium - Result Question 16

####17. Value of KP in the reaction

MgCO3(s)MgO(s)+CO2(g) is

[2000]

(a) KP=PCO2

(b) KP=PCO2×PCO2×PMgOPMgCO3

(c) KP=PCO2×PMgOPMgCO3

(d) KP=PMgCO3PCO2×PMgO

Show Answer

Solution:

  1. (a) MgCO3 (s) arrowMgO (s) +CO2 (g)

Misplaced & are solid and they do not exert any pressure and hence only pressure exerted is by CO2. Therefore KP=PCO2
