Interpretation Introduction

Interpretation : The composition of the equilibrium mixture should be calculated for the reaction of $\text{CO}$ and ${\text{H}}_{\text{2}}\text{O}$ to form ${\text{CO}}_{\text{2}}$ and ${\text{H}}_{\text{2}}$ . $\text{0}\text{.250 moles}$ of $\text{CO}$ react with $\text{0}\text{.250 moles}$ of ${\text{H}}_{\text{2}}\text{O}$ in a $125\text{ mL}$ flask at $900\text{ K}$ with $K_c$ as $\text{1}\text{.56}$ .

Concept Introduction : Equilibrium is the stage of a reversible reaction at which the rate of the forward reaction is equal to the rate of backward reaction.

  $K_p$ or $Kc$ are the equilibrium constants for the reaction which are the ratio of gaseous and aqueous products and reactant molecules.

  $A +B \rightleftharpoons C+D$

  $K=Kc=\frac{[aC][aD]}{[aA][aB]}$

  $K=Kp=\frac{[PC][PD]}{[PA][PB]}$

Here ‘a’ represent the active mass and ‘P’ represents the partial pressure.
