For the SN1 reaction between water (H20) and t-butyl bromide (Me3C-Br), indicate the effect that each change below will have on the RATE of the reaction. Answers are either: rate will increase (1), rate will decreasse (D), or reaction rate will show no change (NC). Enter I, D, or NC in each blank. 1. The concentration of t-butyl bromide decreases. 2. The temperature of the reaction is raised. 3. The nucleophile is changed from H20 to NH3. 4.1-bromobutane is used...
