This is a reaction between Tetrabutyl bromide as well as NaOH- with an indicator of .1% bromo-phenol blue. Explain the reaction is timed as well as whenever the solution changes from blue to yellow the timer were stopped.
OH + (CH3)3CBr (CH3) 3COH + Br
For trial one the molarities are T-butyl=.015M and NaOH=.005M the time the reaction took in seconds was 26.78(s). Which morality utilizes to determine the rate?
