The following data were collected for the reaction of tbutylbromide (CH3)3CBr) with hydroxide ion at 55 degrees Celsius: equation: (CH3)3+CBr+OH-=> (CH3)3COH+Br-1 exp (CH3)3CBr initial [OH]- initial Rate(M/S) 1 .10 .10 1.0*10^-3 2 .20 .10 2.0*10^-3 3 .30 .10 3.0*10^-3 4 .10 .20 1.0*10^-3 5 .10 .30 1.0*10^-3 Then Dtermine the rate law for the reaction. And then calculate the rate constant k for the reaction.
