EPRI EXAM STUDY QUESTIONS
WITH CORRECT ANSWERS!!
Reduction reaction
-substance gains electrons or is reduced
-reducing agent supplies additional electrons
Oxidation reaction
-substance loses electrons or is oxidized
-oxidizing agent takes away electrons
What model explans the factors that affect reaction rates
collision theory
What does an increase in temperature do to reaction rate
increase it
What does the presence of a catalyst do to reaction rate
increase it (lower activation energy)
What does an increase in concentation do to reaction rate
increase it (directly proportional)
What forms when an acid and base are combined?
water, a salt, and varying amounts of thermal energy
How can suspended solids be removed?
, mechanical process, filtration
The higher the temperature, the higher the _______?
solubility
What solutes become less soluble at higher temperatures?
cobalt and nickel
What affects gas solubility?
pressure and temperature
When temperature is near freezing or boiling, gases are...
less soluble (heat decreases solubility)
Some problems caused by impurities:
-corrosion
-fouling
-plugging
-mechanical binding
-radiation dose
Where does boiling occur in BWR
reactor core
Where does boiling occur in PWR
steam generators
An easy way of detecting impurities:
conductivity (many dissolved solids are ions)
Why do metals corrode?
They have more electrons than they want and can give up some to have a complete outer shell
How are metals naturally found?
