Answer :
- Kc for the a) reaction:
[tex]Kc=\frac{\lbrack CO\rbrack^2}{\lbrack CO_2\rbrack^{}}[/tex]- Kc for the b) reaction:
[tex]Kc=\frac{\lbrack HI\rbrack^2}{\lbrack H_2S\rbrack}[/tex]- Kc for the c) reaction:
[tex]Kc=\lbrack O_2\rbrack[/tex]To write the expression for the equilibrium constant (kc), it is important to remember that:
- The concentration of the products is multiplied in the numerator, while the concentration of the reactants is multiplied in the denominator.
- Only the concentrations of the gaseous and/or dissolved species should be included.
