12)When the temperature is doubled. what is relation between the times of reactions for two temperatures?

11)Define elementary and non elementary reaction.

10)Why it is good to use recycled plug flow reactor for autocatalytic reactions when high conversion levels are required?

9)Why there is reaction is not possible, when an auto catalytic reaction is performed in the plug flow reactor?

9)At present we have 90% conversion of the liquid feed (n-1. CA0-10 mol/l) to our mixed flow reactor with a recycle of product(R-2). If we shut off the recycle stream, by how much the conversion decreases for the same processing rate?

8)What is prerequisite to find the minimum reactor for any given different combinations?

7)"For a liquid phase reactions, the residence times for the ideal batch and plug flow reactors are same", State the reason for this statement.

5)Write all the factors that are influencing the rate of reaction.

4)What are the different contacting patterns?

3. For a gas reaction at 400K, the rate is expressed a dpA/dt 3.66 atm.h-. What is the unit for the rate constant?
