Two different proteins X and Y are dissolved in aqueous solution at 37 °C. The proteins bind in a 1:1 ratio to form XY. A soluti

aleksklad [387]

Answer:

Kc of reaction is 20.

Explanation:

The two proteins are X and Y.

The [X] = 1mM

[Y]=1mM

At equilibrium, [X] = 0.2mM [Y] = 0.2mM

we know that equilibrium constant is:

Kc= $\frac{[Products]}{[Reactants]}=\frac{[XY]}{[X][Y]}$

[XY]= 1-0.20=0.80 mM

putting values:

Kc= $\frac{0.80}{0.20X0.20}=20$
