How do you work out the rate constant K?

It says to use the formula: rate=k[MnO4(aq)][H2C2O4(aq)]

But what does this formula mean?

If you know the rate, you can rearrange the equation find k.
i.e k= rate/ [MnO4][H2C2O4]

k is the proportionality constant which relates the concentration of the reactants to the rate. this means that k will always be the same number provided that conditions stay the same

k = rate constant
[] = concentration of
rate is the rate of change of concentration of either a reactant or product in moles per litre per second (minute, hour)
