Please answer ALL questions.
1. If heat is observed as products were formed means that the reaction is ___.
a. endothermic b. endergonic
c. exothermic d. both b and c are correct
In a laboratory experiment, a certain reaction was allowed to reach equilibrium. The
reacting substances produced heat in the course of the reaction. However, one of your
groupmates, unknowingly, increased the temperature of the hot plate where the flask
is placed. He also added the amount of one of the reactants.
2. If a substance that would increase the reaction’s rate would have been added
instead, what will happen to the equilibrium?
a. shift to the left b. shift to the right
c. none of the given options d. no shift
3. Will the equilibrium re-established after one of your groupmates added an increment
in the temperature?
a. yes b. no c. more information required d. none of the given options
4. What equation relates the expression of the equilibrium constant in terms of
pressure and concentration?
a. ideal gas equation b. van’t Hoff equation
c. Arrhenius equation d. Molarity
5. If the coefficients for a reaction are all multiplied by 2, the equilibrium constant will
be
a. equal to Kc x 2 b. equal to Kc over 2
c. unchanged d. equal to Kc
