Question

a Sapling Learning macmillan learning e following reaction is a single-step, bimolecular reaction: CH, Br NaOH CH,OH Na Br When the concentrations of CH3Br and NaOH are both 0.135 M, the rate of the reaction is 0.0050 M/s (a) What is the rate of the reaction if the concentration of CH3Br is doubled? Number (b) What is the rate of the reaction if the concentration of NaOH is halved? Number (c) What is the rate of the reaction if the concentrations of CH3Br and NaOH are both increased by a factor of six? Number Tools Map

Explanation / Answer

this is the SN2 reaction

rate is depends on both reactant concentration

rate = k [CH3Br][NaOH]

part A

when concentration of CH3Br double means rate also become double so

0.0050 m/s x 2 = 0.01 m/s

Part B

when concentration of NaOH become double again rate will become double

so

0.0050 m/s x 2 = 0.01 m/s

part C

when both concentrations become double rate will increase four times

4 x 0.0050 m/s

= 0.02 m/s
