This type of question come in our exams usually that.
If the Reaction
P+Q → R + S
is described as being of zero order with respect to P, it means that.
Answer: THE RATE OF REACTION IS INDEPENDENT OF THE CONCENTRATION OF P.
I want to ask that, what is such thing in this reaction that we should write this answer , I mean how to solve it or what , thanks i have MCAT exams please reply

What you need is to understand what" if rate of reaction is such that
R=kP where k=1, that is zero order. See the reference above
@bobpursley , thanks but i have very little time left for exams so summarize to me in simple way if ur wish bro, tell me how to solve such questions quickly?
To determine the order of a reaction with respect to a particular reactant, you can use the method of initial rates. This involves conducting multiple experiments where the initial concentration of the reactant in question is changed, while keeping the concentrations of the other reactants constant. By measuring the rate of the reaction in each experiment, you can observe how the rate changes as the concentration of the reactant varies.
In the given reaction P+Q → R + S, if the reaction is described as being of zero order with respect to P, it means that the rate of the reaction is independent of the concentration of P. In other words, doubling or halving the concentration of P will not affect the rate of the reaction. This conclusion can be drawn if you have conducted experiments varying the concentration of P and found that the rate of the reaction remained constant.
To solve this type of question, you would need to have conducted experiments with different concentrations of P and measured the corresponding reaction rates. If the rates were found to be invariant with respect to the concentration of P, you would conclude that the order of the reaction with respect to P is zero.
