for the equilibrium H2+CO2<-->H2O+CO
Kc=3.18 at 1106K. if each of the four species was initially present at 3.000M calculate the equilibrium concentration of the CO at this temperature.....
OK I can get as far as equilibrium (final)
H2O=3.000-x
CO=3.000-xx
H2=3.000+x
CO2=3.000+x

substitute the equil.numbers into the KC expression and solve for x.Then add 3.000 or subtract x from 3.000 to arrive at individual concentration...

This is the bit I don't know how to do Could some one please go through it step by step please and show me how to get final answer...

Thanks Andy

  • chemistry -

    see below at original post. I have two scenarios there
    1. if you did not solve the equation.
    2. if you did solve and obtained a value for x.
