Question

Write the rate law expression for the reaction 2HI → H2 + I2, if the order of the reaction is zero.

Hint:

In a zero-order reaction, the rate is constant and does not depend on the concentration of reactants.

Answer 1

For a zero-order reaction, the rate law expression is: \[ \text{Rate} = k \] where \(k\) is the rate constant. The rate is independent of the concentration of reactants.
