WebIn conclusion, simply saying, the reaction rate is generally highest at the beginning of a reaction, when the concentration of the substances reacting is highest. We can identify 5 different factors affecting the speed of chemical reactions, namely temperature, pressure, catalist effects, phase and surface effects as WebIf the concentration of iodide ion is doubled, the rate of forming tert-butyl iodide will: (hint: consider mechanism, i.e. how is the product formed?) (A) Double.(B) Increase 4 times.(C) Remain the same. (D) Decrease.(E) None of the above. In SN1 reaction, the rate is independent of the nucleophile involved since the nucleophile is not
