If the rate of reaction of [0.1 M] sodium cyanide with [0.1 M] 2-bromo-2-methylpropane is 1.2 x 10-3 M/s, what would be the effect on the overall rate if the concentration of sodium cyanide is increased to [0.2 M] and the concentration of the alkyl bromide is decreased to [0.05 M]

-The rate of reaction decreases by a factor of two.

Explanation:

-The initial reaction ration of Sodium Cyanide to 2-bromo-2-methylpropane is 1:1

-Increases the mole ratio of of one of the compounds by a factor of x, reduces the rate of reaction by the same factor x.

#We divide the final amount of 2-bromo-2-methylpropane  by the initial amount to obtain the increment factor,x:

Hence, the overall rate of reaction reduces by a factor of 2
