Question

Le Cha^telier's principle concerns the reaction of systems at equilibrium to perturbations that disturb the equilibrium. Le Cha^telier's principle states that systems will always respond to relieve the stress placed upon them. That is, they will respond in such a way so as to return to equilibrium. Chemical reactions can be displaced from their equilibrium positions by changing the concentrations of reactants or products. These changes affect the value of the reaction quotient. Q. The reaction then shifts to increase or decrease Q until it is again equal to the equilibrium constant, K. For the reaction C(s) + H2O(g) H2(g) + CO(g) classify each of the following actions by whether it causes a leftward shift, a rightward shift, or no shift in the direction of the reaction. Drag the appropriate items to their respective bins.

Explanation / Answer

I'm assuming you need help on part B The Equation is C + H20 H2 + C0 So this principle essentially means that whatever you do tothe reactants/products, the reaction will shift to reduce thechange. For example, if you increase Carbon, the reaction willshift right to reduce Carbon. Leftward shifts:add carbon monoxide, remove water, add hydrogen Rightward: remove Hydrogen, remove carbon monoxide, add water No change: remove/add carbon No change when adding/reducing carbon since it is a solid, andsolid have a constant potential regardless of quantity.
