JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics
The number of incorrect statement/s from the following is \(A\). The successive half lives of zero order reactions decreases with time. \(B\). A substance appearing as reactant in the chemical equation may not affect the rate of reaction \(C\). Order and molecularity of a chemical reaction can be a fractional number \(D\). The rate constant units of zero and second order reaction are \(mol\, L ^{-1} s ^{-1}\) and \(mol ^{-1} Ls ^{-1}\) respectively
- A \(2\)
- B \(3\)
- C \(1\)
- D \(4\)
