Please do question 57.a! Not ALL of them.
When a reaction is said to have reached equilibrium, it means A- The reaction in both directions have stopped. B- The rate of the forward reaction is higher than that of the reverse reaction. C- The concentration of reactant and product are equal. D- The concentration of reactant and products do not change over time. E- The rate of the forward reaction is lower than that of the reverse reaction.
when an equilibrium is disrupted (“stressed”) due to changes that a chemist imposes on the system, Le Chatelier’s Principle predicts that the equilibrium will shift in the direction that will undo as much of the change as possible. For instance, if a particular reactant compound is removed through some chemical means, then the equilibrium will shift to favor the reactants, so as to replace some of the lost compound. In this lab, you will observe the effects of stress on the tetrachlorocobaltate(II)/hexaquocobalt(II) equilibrium shown below: CoCl42-(solv) + 6 H2O(solv) Co(OH2)62+(solv) + 4 Cl-(solv) blue pink The (solv) means a solvated species. In this system, ethanol is the solvent. This means that water can not be excluded from the reaction quotient any longer, since it is now a solute in ethanol and therefore has a measurable concentration. The color of the solution provides a visual clue about the dominant cobalt species…
