direction is favored in the first reaction, and the forward
direction is favored in the second reaction. Choice (B)
is correct.- C Think of Le Chatelier’s principle, and look at what’s happening
here. Someone increases the concentration of the product O 2 in a reaction at
equilibrium. This means that the concentration of the other product, SO 2 ,
will decrease, and the concentration of the reactant(s) will increase. Choice
(C) is the correct answer.
- B Don’t fall into the temptation trap. You’ve probably heard the
phrase “not consumed by the reaction” in connection with catalysts, in
kinetics. But here they’re asking about an activated complex. An activated
complex is quickly broken down to form the products of a reaction. Choice
(B) is the correct answer.
