JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics
The given plots represent the variation of the concentration of a reactant \(R\) with time for two different reactions \((i)\) and \((ii).\) The respective orders of the reactions are
- A \(1,1\)
- B \(0,2\)
- C \(0,1\)
- D \(1,0\)
Answer & Solution
Correct Answer
(D) \(1,0\)
Step-by-step Solution
Detailed explanation
For first order reaction \(\ln \,{[R]_t}\, = \, - \,Kt\, + \,\ln \,{[R]_0}\) For zero oeder reaction \({[R]_t}\, = \, - \,Kt\, + \,{[R]_0}\) Where \('R'\) is reactant.
