ahhhh okay cool. As A is 2nd order (as shown by the ^2), it means that there are 2 moles of A for every 1 mole of everything else in the rate-determining step.
Only substances in the Rate-Determining step are included in the rate equation, so perhaps X is a catalyst that is regenerated later.
E.g. 2A + X ---> C + AX then B+ A + AX --> D + X giving 3A + B --> C + D overall.

Hope this kinda makes sense?
ohhh ok, this makes much more sense than to what I originally thought it was. Thank you!
Not a problem! It's been a while since I did A -Level Chem (about 4 weeks lol) but I think that's the general gist of it. The main thing to remember is that some substances do not take part in the overall reaction (i.e. are regenerated) but may be in the rate determining step as catalysts. The only thing I'm unsure on is that catalysts are usually zero order. If what I've said is wrong I'm sorry!
