    The reaction \[2NO(g)+{{O}_{2}}(g)2N{{O}_{2}}(g)\] is of first order. If volume of reaction vessel is reduced to the rate of reaction would be

    A)  \[\frac{1}{3}\] times                                     

    B)  \[\frac{2}{3}\] times

    C)   3 times                              

    D)  6 times

    Correct Answer: C

    Solution :

                     For the following reaction, \[2NO(g)+{{O}_{2}}(g)\xrightarrow{{}}2N{{O}_{2}}(g)\] When the volume of vessel change into \[\frac{1}{3}\], then concentration of reactant become three times. The rate of reaction for first order reaction is directly proportional to   concentration. Therefore, rate of reaction will increase three times.
