Chemistry q and k relationship

WebAug 28, 2024 · Q is different from Kc because Kc indicates the ratio of products to reactants at equilibrium while Q indicates the ratio of products to reactants at any time during the reaction (such as when it has not yet reached equilibrium) we can then use Q to figure out which direction a reaction is sitting toward by comparing … WebWe can use the information given and the Nernst equation to calculate E cell. Moreover, because the temperature is 25°C (298 K), we can use Equation 11.4.5 instead of Equation 11.4.2. The overall reaction involves the net transfer of two electrons: 2Ce4 + ( aq) + 2e − → 2Ce3 + ( aq) 2Cl − ( aq) → Cl2 ( g) + 2e −.
