Question

The reaction, A + B → C, has zero order. Write the rate equation.

Answer 1

For a zero-order reaction, the rate is independent of the concentration of reactants.

The given reaction is A + B → C 

Since it is zero order, the rate equation is Rate = k

Where:

k is the rate constant

The concentrations of A and B do not appear in the rate law because the reaction rate does not depend on them.
