If for a reaction in which `A(g)` converts to `B(g)` the reaction carried out at const.
`V` & `T` results into the following grapg.

Options

A. then the reaction must be `A(g) rarr 3B (g)` and is a first -order reaction.
B. then the reaction must be `A(g) rarr 3B(g)` and is a second-order reaction.
C. then the reaction must be `A(g) rarr 3B(g)` and is a zero-order reaction.
D. then the reaction must be `A(g) harr 3B(g)` and is first-order reaction.

Answer

C

Explanation

From the given graph it is clear that the concentration decrease linearly with time zero-order reaction and `A rarr 3B` type.
