Suppose we founf that the reaction of Red#3 with bleach is 1st-order in hypochlorite. The observed rate constant(k-observed) for one of the trials was measured to be 0.00400 s^-1. If the concentration of hypochlorite was fixed at 0.134 M, calculate the specific rate constant (k) for the trail.
1) The standard potential of the cell Ag(s)|AgCl(s)\\Cl-(aq)||Ag (aq)|Ag(s) is 0.58 V at 25 °C. Calculate the equilibrium constant for the cell reaction.
