How Do Coefficient Changes Affect Equilibrium Constants?

[Johnyi]

Homework Statement

The reaction below has a equilibrium constant of Kp = 2.26 x 10^4 at 298 K
CO(g) + 2H2(g) <=>CH3OH(g)

Calculate Kp for each of the reactions and predict whether reactants or products will be favored at equilibrium

A. (1/2)CO(g) + H2(g) <=> (1/2)CH3OH(g)

The Attempt at a Solution

I know i have to multiply all the coefficients by something..but i just don't know by what. How can i tell?

Im not sure what you mean by this. Can you explain more please

 

[Borek]

Write formulas for equilibrium constants and see if there is no some simple operation that can convert one into the other.
