- Give the reaction mechanism of the given chemical reaction (synthesis of methyl salicylate)arrow_forwarddraw the mechanisms of the reactions.arrow_forwardSuppose the formation of tert-butanol proceeds by the following mechanism: step elementary reaction rate constant 1 CH33CBr (aq) → CH33C+ (aq) + Br− (aq) k1 2 CH33C+ (aq) + OH− (aq) → CH33COH (aq) k2 Suppose also k1 ≫ k2 . That is, the first step is much faster than the second.arrow_forward
- The enzyme-catalysed conversion of a substrate at 25 oC has a Michaelis constant of 0.045 mol dm-3. The rate of the reaction is 1.15 mmol dm-3 s-1 when the substrate concentration is 0.110 mol dm-3 . What is the maximum velocity of this reaction?arrow_forwardWhat is the mechanism for the reaction?arrow_forwardThe bromination of aceton is acid –catalyzed. CH3COCH3 + Br2 + H+ ---------> CH3COCH2Br + 2H+ + Br- The rate of disappearance of bromine was measured for several different concentrations of acetone, bromine, and H+ ion at a certain temperature. A B C [ CH3COCH3] [Br2] [ H+] Rate of disapperance [ Br2] 0.30 0.050 0.050 5.7 x 10 -5 0.30 0.10 0.050 5.7 x 10 –5 0.30 0.050 0.10 1.2 x 10 -4 0.40 0.050 0.20 3.1 x 10 -4 Write the rate law. Find the rate constant. Determine the half-life of the reaction if the [A]o = 0.50M ; [B]o = 0.40 M; [C]o = 0.6 M. ( Half-life is based on over all order of the reacaction)arrow_forward
