An effervescent tablet dissolves much more rapidly in a glass of water if it is broken into pieces than if the entire tablet is placed into the glass. What is the best explanation for this observation?
A. The surface area of the tablet increases when it is broken into pieces. Therefore, the reaction rate increases.
B. Breaking the tablet into pieces raises the temperature of the reaction. Therefore, the reaction rate increases.
C. The concentration of the tablet increases when it is broken into pieces. Therefore, the reaction rate increases.
D. A catalyst is added to the wate

Best ResponseYou've already chosen the best response.1Hm, this one is worded a bit strangely. The tablet would have a larger surface area once it is broken which would enable it to dissolve faster.

Best ResponseYou've already chosen the best response.1But that is not a reaction, just dissolving.

Best ResponseYou've already chosen the best response.1There is no mention of a catalyst, so D is out.

Best ResponseYou've already chosen the best response.1And the concentration doesn't increase when the tablet it broken. It is the same concentration. So C is out.

Best ResponseYou've already chosen the best response.1I think what they are looking for is A, but it is honestly not a very good question.
