1. which scneario will result in the fastest reaction between 5
grams of Zn and excess HCL (aq)
a. use a 5 gram zinc cylinder
b. carry out the rxn in an ice bath
c. use 5 grams of Zn crushed into powder
d. decrease the concentration of HCl
2. The rxn 2SO2 + O2 <--> 2SO3 reaches Eq and then
pressure of reaction container increases. What effect will increase
in pressure have on rxn?
a. concentration of SO3 increases
b. concentration of SO3 decreases
c. Equilbirium constant decreases
c. Equilbirium constant increases
3. Which forms of energy can be released during a chemical
reaction?
a. only thermal
b. only nuclear
c. thermal, sound, light energy
d. thermal, nuclear, light energy
