I understand question number 2 but why is question 19's answer not C?

What type of substitution name would you use to describe the reaction of 19?  Think about the rate-limiting step in that reaction.

Since it is tertiary it will be sn1 so only the R-Br concentrations will have an effect on the rate.

That is correct.
