The inversion of cane sugar is first order in [sugar] and proceeds with half-life of 600 min at pH=4 for a given concentration of sugar. However , if pH=5, the half-life changes to 60 min. The rate law expression for the sugar inversion can be written as

`rate=k[sugar]^(1)[H^+]^(2)`

`rate=k[sugar][H^(+)]^(1)`

`rate=k[sugar][H^(+)]^(4)`

`rate=k[sugar][H^(+)]^(0)`
