    The    rate    for    the    reaction\[RCl+NaO{{H}_{(aq)}}\xrightarrow{{}}ROH+NaCl\]is given by rate \[=k[RCl]\], the freezing point of the reaction is:

    A)  unaffacted by increasing the temp. of the reaction

    B)  decreased on increasing the temp. of the reaction

    C)  halved on reducing the concentration of \[RCl\] to half

    D)  doubled    on    doubling    the concentration of \[NaOH\]

    Correct Answer: C

    Solution :

                    \[r=k[RCl]\] If  \[[RCl]=\frac{1}{2}\], then rate \[\frac{r}{2}\]
