The kinetics of a reaction A + B + C → D are being studied. By comparison with the first experiment it is found that
i) Keeping [B]0 and [C]0 constant and increasing [A]0 by a factor of 4 causes the reaction to go eight times faster initially.
ii) Keeping [A]0 and [C]0 constant and decreasing [B]0 by a factor of 2 causes the initial rate to increase by a factor of 1.414.
iii) Doubling the initial concentrations of A, B, and C in one experiment causes the reaction to go twice as fast initially.
The exponent in the rate law for [A] is?
- A. -3/2
- B. 1/2
- C. -1/2
- D. 0
-
E. 3/2

In a study of the reaction A + B + C → products at constant temperature, it was found that: 1. Holding [A] and [B] constant and halving the concentration of C causes the rate to proceed 2.828 times faster. 2. Holding [B] and [C] constant and doubling the concentration of A causes the reaction to proceed four times faster. 3. Doubling the concentrations of A, B, and C simultaneously, causes the reaction to proceed 1.414 times faster. The experimental...

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...
