Question

Please help asap,

10. In the following diagram, what do the capital C and D represent? What do the capital A and B represent? What the lower case letter represent
aA+bB⇔cC=dD, K↓eq=[C↑c][D↑d] / [A↑a] [B↑b]

12. A chemical reaction is at equilibrium, which direction does the equilibrium shift if more product is added?

13. A chemical reaction is at equilibrium, which direction does the equilibrium shift if more reactant is added?

14. The following Chemical equation is an exothermic reaction: 2KO2 + H2O ⇔ 2KOH + 1.5O2. If you were to cool down this exothermic reaction, in which direction will the equilibrium shift?

Answer 1

10. Capital C and D represent products of chemical reaction, the capital A and B represent reactants, the lower case letter represent coefficients (how many atoms or molecules in chemical reaction).
12. According to Le Chatelier's principle (if the concentration is changed, that will shift the equilibrium to the side that would reduce that change in concentration) the equilibrium shift to the left.
13. According to Le Chatelier's principle the equilibrium shift to the right.
14. According to Le Chatelier's principle (When the reaction is exothermic, heat is included as a product) the equilibrium shift to the right.
