hey guys i have a question that i cant work out how to calculate be great if you can help.

 

Question:

 

A mixture of 5.00E-3 mol of H2 and 1.00E-2 mol of I2 is placed in a 5 L container at 448 degrees C and allowed to come to equilibrium. Analysis of the equilibrium mixture shows that the concentration of HI is 1.87E-3 M.

 

Calculate Kc at 448 degrees C for reaction

 

H2(g) + I2(g) <-> 2 HI

 

Cheers

See if the example here can help :)

 

Cheers,
