(c) Thermal decomposition of HI on gold surface

(d) Inversion of cane sugar in the presence of mineral acids

This question was addressed to me in unit test.

I need to ask this question from Integrated Rate Equation and Half Lives in portion Reaction Dynamics of Engineering Chemistry I

Answer 1

Correct option is (d) Inversion of cane sugar in the presence of mineral acids

To explain I would say: Inversion of cane sugar in the presence of mineral acids is not an example of zero order reaction. All the other options are the example of zero order reaction.
