Equilibrium concentration of reactants and products:
Explanation:
The equilibrium constant of the reaction =![K_c=1.80\times 10^{-2}](/tpl/images/0553/9717/74b2f.png)
Mole sof HI = 0.372 mol
Volume of the vessel = 1.00 L
Initial concentration of HI =![\frac{0.372 mol}{1.00 L}=0.372 M](/tpl/images/0553/9717/dcc2e.png)
0.372 M
At equilibrium
(0.372-2x) M x x
An expression of an equilibrium constant will be given as;
Solving for x;
x = 0.03935
