The rate for the reaction, RCl+NaOH(aq) ROH+NaCl is given by rate =k[RCl]. The rate of the reaction is [Manipal 2003]

JEE Main Chemistry question

The rate for the reaction, RCl+NaOH(aq)\rightarrow ROH+NaCl is given by rate . The rate of the reaction is [Manipal 2003]

(A)Unaffected by increasing the temperature of the reaction
(B)Decreased on increasing the temperature of the reaction
(C)Halved on reducing the concentration of to halfCorrect
(D)Doubled on doubling the concentration of

Answer: (C)

Solution

Since rate , the reaction is first order in and zero order in , so the rate is directly proportional only to — halving halves the rate, matching option (C). Changing
