Hi, im doing my chemistry coursework for salters b at the moment and needed to know what the rate equation is between magnesium and hydrochloric acid and what the orders are with respect to each reactant. I've tried researching on the internet but cant find it anywhere? If anyone could help then that would be amazing

Rate equations can only be derrived from experimental data. You'll probobly be best of just getting the different rates at different concentrations yourself.

you cannot include magnesium in the rate equation as it is a solid.

so do i just leave that out of the rate equation altogether so only hydrochloric acid is involved?

i've done experimental data, i just wanted to see if my results were the same as the expected results.

Yes. The rate equation involves concentrations. Solids cannot have a 'concentration'.
