For certain chemical reaction \(X \rightarrow Y\), the rate of formation of product is plotted against the time as shown in the figure. The number of Correct statement/s from the following is \(.......\). \((A)\) Over all order of this reaction is one \((B)\) Order of this reaction can't be determined \((C)\) In region\(-I\) and \(III\), the reaction is of first and zero order respectively \((D)\) In region\(-II\), the reaction is of first order \((E)\) In region\(-II\), the order of reaction is in the range of \(0.1\) to \(0.9\).

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
