Assuming no other changes,what effect on the rate would result from simultaneously doubling the concentrations of both 2-iodopentane and sodium acetate?

Question

Consider the S_N2 reaction of 2-iodopentane with CH₃CO₂- ion.

Consider the S<sub>N</sub>2 reaction of 2-iodopentane with CH<sub>3</sub>CO<sub>2</sub>- ion. Assuming no other changes,what effect on the rate would result from simultaneously doubling the concentrations of both 2-iodopentane and sodium acetate? A) No effect. B) It would double the rate. C) It would triple the rate. D) It would increase the rate four times. E) It would increase the rate six times.

Assuming no other changes,what effect on the rate would result from simultaneously doubling the concentrations of both 2-iodopentane and sodium acetate?

Quizplus · Accepted Answer

The rate of a reaction is dependent on the concentrations of the reactants. Doubling the concentrations of both 2-iodopentane and sodium acetate will result in a four-fold increase in the rate of the reaction. This is because the reaction is second order with respect to 2-iodopentane and first order with respect to sodium acetate, so doubling the concentration of each reactant would result in an overall rate increase of 2 x 2 = 4 times.
