SAT Subject Test Chemistry,10 edition

(Marvins-Underground-K-12) #1
(A) What    is  the order   with    respect to  A?
(B) What is the order with respect to B?
(C) What is the rate equation?
(D) What is the overall order of the reaction?
(E) Calculate the rate constant.

4 . Consider the following chemical reaction and experimental data:


A   (aq)    →   B   (aq)    +   C(g)

Trial   1 Trial 2
[A] (mol/L) Rate [A] (mol/L) Rate
0.10 0.6 0.10 0.9
0.20 0.6 0.20 0.9
0.30 0.6 0.30 0.9
0.40 0.6 0.40 0.9

(A) What    is  the rate    expression  for trial   1?
(B) What is the rate constant for trial 1?
(C) What is the most likely reason for the increased rate in trial 2?

5 . Consider the following reaction and experimental data:


SO 3 + H 2 O → H 2 SO 4


[SO 3 ] (mol/L) [H 2 O] (mol/L) Rate
Trial 1 0.1 0.01 0.013
Trial 2 0.2 0.01 0.052
