Why is t- butyl bromide more reactive towards `S_N 1` reaction as compared to n- butyl bromide?

Write the IUPAC name of t-butyl bromide.

Assertion: In the reaction of tert-butyl bromide with aq. KOH, rate becomes double by increasing the concentration of both aq. KOH and tert-butyl bromide Reason: Rate of reaction is, rate = kſtert butyl bromide) [OH^(-)] .

Assertion: tert-butylbromide undergoes S_(N)1 nucleophilic substitution readily than n-butyl bromide. Reason: It proceeds by the formation of stable carbocation.
