Q 4: Transition state theory approaches the problem of calculating reaction rates by concentrating on the idea of______.
Q 5 In a first-order reaction (A → Products) the reaction becomes slower as it proceeds, because the concentration of A _________, and the rate is _______.
Q 6: A homogeneous liquid phase reaction
A\rightarrow R;\;\;-r_A=kC_A^2takes place with 50 % conversion in a well-mixed reactor operating isothermally. What will be the conversion if the reactor is replaced by a plug flow type of equal size all else remaining the same?
Q 7: Consider the set -of elementary reactions
A\xrightarrow{k_1}B
A+B\xrightarrow{k_2}C
A+D\xrightarrow{k_3}2E
At time t = 0, a batch reactor is filled with a mixture of A and D. What is the relation between the concentrations of B and D after a time t?
