Question

Which one of the following plots is true for the first order decomposition of $N_2{O}_5$ ?

• A.
• B.
• C.
• D.

Answer 1

Answer: (D)

If a straight line is obtained in rate versus concentration graph, then the reaction is of first order, ie,
Rate $=k[R]$
In the following graph, the graph $(d)$ is true for the first order, decomposition of $N_2{O}_5$. In this graph a straight line is obtained when it is plotted rate versus concentration, ie,
Rate $=k\left[N_2{O}_5\right]$
Rate of decomposition of $N_2{O}_5$ as a function of $\left[N_2{O}_5\right]$.
