Question

1- High activation energy

A)Temperature Sensitive

B)Temperature insistivity

C)High viscosity

D)Low viscosity

2- Distillation is designed for ?

A)Solubility

B)Volatility

C)Viscosity

D)Fractionation

Answer 1

1) In reaction kinetics engineering it is known that reaction with high activation energy are more temperature sensitive.

Why ?

Because higher value of activation energy means larger value of energy required for the intermediate step. And providing temperature activates the molecule and bring them closer to the intermediate step.

So , Option A is the correct answer.

2 ) distillation is the process used for separating different components of a feed mixture based on their boiling points .

Fractionation means separation of a mixture into different components . therefore distillation is used for fractionation. Option D is correct answer.
