The reaction of 1-bromopropane with sodium iodide gives 1-iodopropane. What is the effect of doubling the concentration of NaI on the rate of the reaction?
A) the rate remains the same
B) the rate decreases by a factor of 2
C) the rate increases by a factor of 2
D) the rate increases by a factor of 4
