For the liquid phase parallel reactions:
R, rR = K?.CA2; E? = 80 KJ/mole
S, rS = K?.CA ; E? = 120 KJ/mole
The desired product is R. A higher selectivity of R will be achieved, if the reaction is conducted at - Which of the following is a controlling factor in very fast heterogeneous reaction?
- The catalytic converter for conversion of SO₂ to SO₃ by contact process should have a feed with SO₂ content between
- In which of the following gaseous phase reactions, the equilibrium of the reaction remains unaffacted by pressure changes ?
- A multiple reaction may be classified as a __________ reaction.
- The single parameter model proposed for describing non-ideal flow is the __________ model.
- Pick out the wrong statement.
- The exit age distribution of fluid leaving a vessel is used to know the
- In case of staged packed bed reactors carrying out exothermic reaction, use
- The rate expression for a heterogenous catalytic reaction is given by, - rA = K.KA PA(1 + KA.PA + Kr.PR), where K is surface reaction rate constant and KA and KR are absorption equilibrium constants of A and R respectively. If KR PR >> (1 + KA PA), the apparent activation energy EA is equal to (given E is the activation energy for the reaction and ΔHR and ΔHA are the activation energies of adsorption of R and A)
