Suppose that 0.25M IBr in a flask, the Kc at the given temperature is mathematically given as
Kc=0.00336814413
Generally, the equation for Chemical Reaction is mathematically given as
2IBr--->T2+8r_2
Therefore
K={I2*Br2}/IBR^2
K=x^2/(0.25-2x)^2
Kc=0.13M^2/0.224M^2
Kc=0.00336814413
In conclusion, the Kc at the given temperature
Kc=0.00336814413
