    For a reaction\[[R]\xrightarrow{{}}P\]a graph of [R] against time is found to be a straight line. What is the order of this reaction?

    A)  Second order    

    B)  Third order

    C)  First order      

    D)  Zero order

    Correct Answer: D

    Solution :

     Since, the graph of \[[R]vs\]time, t is straight line, the order of reaction must be zero because for zero order reaction, integrated rate equation is \[[R]=-kt\,+\,\,[{{R}_{0}}]\] The slope of this graph is negative.
