Q

Reaction rate of hydration

A

Fast

17
Q

Purity of ethanol in hydration

A

Pure, no need for fractional distillation

18
Q

Compare fermentation to hydration

A
19
Q

What does carbon neutral mean

A

Activity which produced No net carbon emissions to the atmosphere

It releases the same amount of CO2 when it was burned as was taken in from the atmosphere when the plants grew and photosynthesised.

A
21
Q

Conditions for the dehydration of alcohols

A

Hot, concentrated H2SO4/H3PO4

22
Q
