How would the rate of disappearance of ethyl bromide change if the solution were diluted by adding an equal volume of pure ethyl alcohol to the solution? The reaction between ethyl bromide (C2H5Br) and hydroxide ion in ethyl alcohol at 330 {K}, {C2H5Br}(alc) + {OH-}(alc) -->{C2H5OH}(l) + {Br-}(alc), is first order each in ethyl bromide and hydroxide ion. When {C2H5Br} is 0.0477 {M} and {OH-}] is 0.100 {M}, the rate of disappearance of ethyl bromide is 1.7 x 10^{-7} {M/s}
Jerry forgot to record the actual molar concentration of the standard HCL solution ( which was actually 0.044M), However to complete the calculations quickly the 0.05 M concentration was used. Will the reported molar solubility of the Ca(OH)2 be t..
