How can we identify the rate of reactions using oxidation & reduction reactions that occurs when metals react with dilute acids?

The more easily an elements forms ions, the quicker rate of reaction, EG: - Magnesium reacts rapidly with dilute acid -> easily forms the ion Mg^2+ - Zinc reacts quite rapidly with dilute acid -> quite easily forms the ion Zn^2+ - Iron reacts slowly with dilute acids -> less easily forms Fe^2+
