P - C
R - D
Ohh yeah R is A. idk why I typed D.
But P - A,C idk how.
For R it should be first order in A. And coefficients of A and B should be same.
Nothing given about initial concentrations of A and B right?
Nope bro nothing about initial conditions
My doubt is all we need is a first order reaction,
T1/2 is independent if initial concentration anyways right?
But Option C is zero order wrt to A right?
Oh right didn't read half life is for A
So answer is wrong or some deeper concept
