I encountered a question where it only gives the balanced equation, temperature, and Keq (equilibrium constant) value.
No values for concentration or any value that could be used to calculate concentration were given, so I don't think I could use the usual formula for Keq ([reactants]/[products]).
Can anyone help me?
Here's the specific question, if it would help:
Given :
Temperature : 1500 degrees Celcius
Equilibrium Constant : 0.1764
Balanced equation: CO + 3 H2 <=>CH4 + H2O
Need:
Equilibrium Constant for CH4 + H2O <=> CO + 3H2

When you have a rxn reversed then you invert the K such as (1/.1764)
If there are coefficients in front of the molecules, then raise k to the power of coefficients.
Good luck

No. the answer will be unfavorable a million.80. you do not turn the truly numerical fee... you purely turn the signal of the equilibrium consistent. A + B = C ok=a million.80 C= A + B ok= -a million.80

You have the constant right in front of you. The reaction is in equilibrium so the rate of the forward reaction equals the rate of the reverse reaction. I believe this is correct, so give it a whirl. The inverse is not true for an equilibrium reaction. Hence the name equilibrium. The inverse would be for a non-equilibrium reaction. Check out gen. chem again or physical chem.

k' = [CO] * [H2] / ([CH4] * [H2O]) = 1/k
