Assuming no other changes, what effect on the rate would result from simultaneously doubling the concentrations of both butyl bromide and OH - ion?
CH3CH2CH2CH2Br + OH - → CH3CH2CH2CH2OH + Br -
A. No effect.
B. It would double the rate.
C. It would triple the rate.
D. It would quadruple (4x) the rate.
E. It would sextuple (6x) the rate.
