[e] is the correct option for it.
order depends upon the power concentration like if
rate = [concentration]^ n
then reaction is called n order .like wise
we apply the concept at low concentrations of A means [1+PA +PB] = 1
and for high concentration of A [1+pA+pB] = pA

The following reaction was studied experimentally at 25 °C. S2O82(aq) + 21'(ag) = 12(aq) + 2SO4 (aq) The reaction was found to be first order with respect to I and first order with respect to S208". A reaction was performed with [1] = 0.080 M and [S208²-] = 0.040 M. The initial rate of formation of 12 was found to be 1.25 x 10-M St. Provide an expression for the rate law for this reaction and determine the initial rate...

Please show work and explain: The reaction A + B → C is studied similarly to our study of phenolphthalein fading kinetics. The corresponding rate law is Rate = k[A]m[B]m In this particular experiment, the concentration of A is sufficiently high that the pseudo-order rate law: Rate = k1[B]n can be written, where k1 = k[A]m. If the study establishes that the reaction is first order in B (n = 1) and that the pseudo rate constant k1 has the...
