2 Ch(aq) + Em(aq) + Is(s) + T(g) ⇄ Ry(aq) + 3 Ro(s) + 4 X(g) ΔHrxn=35.6 kJ/mol
Name three things that you could do to make the equilibrium below run to the
left.
What direction would the reaction shift if you added water?
Please help me!!
I don't have any idea what Ch and Ry stand for; perhaps they are just "something."
But three things to do to shift the equilibrium to the left.
1. Add Ry
2. Decrease Em
3. Cool the rxn since delta H is +.
4. Decrease Ch
To determine three ways to make the equilibrium reaction shift to the left, we need to consider Le Chatelier's principle. According to this principle, if we can manipulate the concentration, pressure, or temperature of the system, we can influence the equilibrium position. Here are three possible ways:
1. Decrease the concentration of products: By decreasing the concentration of the products (Ry(aq), Ro(s), and X(g)), the equilibrium will shift to the left to maintain the balance. This can be achieved by removing some of the products.
2. Increase the concentration of reactants: By increasing the concentration of the reactants (Ch(aq), Em(aq), and Is(s)), the equilibrium will shift to the left to consume the excess reactants. This can be achieved by adding more of the reactants to the system.
3. Decrease the temperature: In an exothermic reaction like this, decreasing the temperature will cause the equilibrium to shift to the left to counteract the decrease in temperature. This can be achieved by cooling down the system.
Now, if water is added to the system, it will act as a reactant. Depending on the specific reaction conditions, the addition of water can dilute the reactants or products, thus affecting the equilibrium position. However, since the reaction is not explicitly mentioned to involve water, it is difficult to determine the exact direction of the shift without more information. Generally, the addition of water might lead to the equilibrium shifting to the right in order to consume the excess water, but it ultimately depends on the specific reaction and the concentrations of the other species in the equilibrium.
