What does Kevin say may happen if the temperature is too high?
The raw materials will become impure
The pressure will drop automatically
The reaction could produce side reactions
The yield will always stay the same
Explanation:
Kevin says that higher temperature might speed up the reaction, but too high a temperature can cause side reactions.
3.
What does Kevin say about increasing pressure?
It can improve yield in some cases
It always damages the reaction
It only works when the temperature is low
It has no effect on the process
Explanation:
Kevin states that increasing pressure can improve yield in some cases.
4.
Why do Sarah and Kevin want to run small tests?
To stop using raw materials with impurities immediately
To avoid discussing pressure changes any further
To compare different conditions before choosing the best one
To prove that temperature does not matter
Explanation:
They say they should test different temperatures carefully and run small tests with the changes so they can find the best conditions.
5.
What else do Sarah and Kevin decide to check besides temperature and pressure?
The purity of the raw materials
