At 1173 K, Keq = 0.0108 for the following reaction: CaCO3(s) ⇄ CaO(s) + CO2(g) The reaction takes place in a 10.0 L vessel at 11
maxonik [38]

Answer:

The amount of calcium carbonate will increase.

Explanation:

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

  • K>Q , reaction will move forward by making more product.
  • K<Q , reaction will move backward by making more reactant.

CaCO_3(s)\rightleftharpoons CaO(s) + CO_2(g)

Equilibrium constant of the reaction = K_{eq}=0.0108

Concentration of CaO=\frac{15.0 g}{56 g/mol\times 10.0L}=0.027 M

Concentration of CO_2=\frac{4.25 g}{44 g/mol\times 10.0L}=0.0096 M

Concentration of CaCO_3=\frac{15.0 g}{100 g/mol\times 10.0L}=0.015 M

Q=\frac{[CaO][CO_2]}{[CaCO_3]}

=\frac{0.027 mol/L\times 0.0096 mol/L}{0.015 mol/L}=0.0174

K_{eq}

This means that equilibrium will move in backward direction by which amount of calcium carbonate will increase.
