Consider reaction,

CaCO3(s)⇌CaO(s)+CO2(g)<br/><br/>Inaclosedcontaineratequilibrium.WhatwouldbetheeffectofadditionofCaCO{CaCO}_{3} \left(s\right) ⇌ \text{CaO}\left(s\right) + {CO}_{2} \left(\text{g}\right)<br /> <br /> In a closed container at equilibrium. What would be the effect of addition of {\text{CaCO}}_{3}ontheequilibriumconcentrationofCOon the equilibrium concentration of {\text{CO}}_{2} ?\text{?}

Options

  1. AIncreases
  2. BDecreases
  3. CData is not sufficient to predict it&
  4. DRemains unaffected&

Correct answer

D. Remains unaffected&

Step-by-step solution

This is a heterogeneous equilibrium. The equilibrium constant for it can be written as: {K }_{c}= \left[{CO}_{2}\right] The concentration of CaCO_{3}& and CaO are assumed to be constant as they are present as solid. Hence, CaCO_{3} has no effect on equilibrium concentration.
