How Do Coefficient Changes Affect Equilibrium Constants?

AI Thread Summary
The discussion centers on calculating the equilibrium constant Kp for a modified reaction involving CO, H2, and CH3OH, starting with a known Kp of 2.26 x 10^4 at 298 K. Participants emphasize the need to adjust the coefficients of the reaction to derive the new Kp. They suggest writing the reaction quotients for both the original and modified reactions to analyze their relationship. The conversation highlights the importance of understanding how changes in coefficients affect the equilibrium constant. Overall, the focus is on determining the favored direction of the reaction at equilibrium based on the calculated Kp.

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)


Homework Equations





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

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...

Thread 'How to find the pH of a galvanic cell (MIT OCW problem set)'

This is the final problem in this problem set from MIT OCW. Here is what I did to try to solve it The table cited in the problem is below We can easily spot the two redox couples that are in the electrochemical cell we are given. The hydrogen-based electrode has standard potential zero, and the silver-based electrode has standard potential 0.22. Thus, the hydrogen electrode, with the lower potential, is the reducing agent (ie, it is where oxidation happens) and is the anode. Electrons...
