Consider the following decomposition reaction and corresponding rate constants, and answer the following two questions.
2 A(aq) ⇌k−1k1 B(aq) + C(aq)
Temperature
k1 (M−1 s−1)
k−1 (M−1 s−1)
1100 K
0.337
3.6×10−6
1500 K
3.48
3.1×10−4
A. What is the value of Kc at 1100 K? Enter a value accurate to three significant figures. For scientific notation, enter 1234 as 1.23e3 or 0.1234 as 1.23e−1.
B. Which of the following statements is correct.
The reaction is exothermic.
The reaction is endothermic.
There is insufficient information to tell if the reaction is endothermic or exothermic.
