Question

Looking at the chemical reaction: [(H3C)2NC6H4]3C+ + OH- --> [(H3C)2NC6H4]3COH , is it reasonable for the crystal violet reaction to occur by a single step mechanism? Why, or why not?

Based on the rate law, rate = k[crystal violet+][OH-], could the crystal violet reaction occur by a single-step mechanism? Why or why not?

Thanks in advance!
