When determining the equilibrium concentrations for the reaction ; a simplifying assumption can be used under certain conditions to avoid solving a quadratic equation. Classify each situation by whether the simplifying assumption can be used or whether the quadratic formula is required. Use simplifying assumptions - Quadratic formula required 1. [AB] = 0.0178 M; 2. [AB] = 0.00204 M; 3. [AB] =0.451 M; = 0.000905 4. [AB] = 0.0174 M; = 0.0000925 5. [AB] = 0.396 M; = 0.00228

When the value of the equilibrium constant is much smaller than [AB], simplifying assumption can be used.

However, if the value of the equilibrium constant is closer to [AB], quadratic formula is required.

a

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
