Question
a. What must happen in order for a reaction to occur? Molecules must
-be the same
-attract one another
-be liquid or gas
-collide
b. What else must happen for molecules to react? Molecules must
-be at room temperature
-be at 1M concentration or higher
-collide with sufficient force
-be polar
c. Which of the following will probably not help a reaction go faster?
-Cooling things down
-Heating things up
-Increasing concentration of the reactants
-Adding a catalyst.
d. For the reaction mA + nB ßà oC + pD, the correct equilibrium constant K =
-[A]^m[B]^n / [C]^o[D]^p
-[C]^o[D]^p / [A]^m[B]^n
-[mA][nB] / [oC][pD]
-[oC][pD] / [mA][nB]
-[mA][nB] / [oC][pD]
-[oC][pD] / [mA][nB]
Explanation / Answer
a)
For a reaction to occur, the molecule must colloid.
Thus, correct option is, colloid.
b)
For molecules to react, the molecules colloid with sufficient force.
C)
Cooling things down will probably not help a reaction go faster.
D)
Expression for K is,
K =[C]^o[D]^p / [A]^m[B]^n
