Liquid A decomposes with nth-order kinetics in a batch reactor A->B, r =kca. the conversion of A reaches 50% in a five minute
1 answer:
Answer:
A) 1
B) 2.5
C) 3.32
Explanation:
The possibility of n=1 is not achievable in 20 minutes and 30 minutes as calculated n=1 for 10 minutes. The same conversion cannot be achieved for the rest of the time which is impossible as 75% conversion and it cannot be achieved at 10 min and 20 min at the same time
A) what is the order of the reaction if it takes 10 minutes to reach 75% conversion
= n ( order ) = 1
B) what is the order of reaction if it takes 20 minutes to reach 75% conversion
= n ( order ) ≈ 2.5
C) what is the order of reaction if it takes 30 minutes to reach 75% conversion
= n ( order ) ≈ 3.32

Answer: A. The reaction takes place in one step.
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
Molecularity of the reaction is defined as the number of atoms, ions or molecules that must colloid with one another simultaneously so as to result into a chemical reaction.
Order of the reaction is defined as the sum of the concentration of terms on which the rate of the reaction actually depends. It is the sum of the exponents of the molar concentration in the rate law expression.
Elementary reactions are defined as the reactions for which the order of the reaction is same as its molecularity and order with respect to each reactant is equal to its stoichiometric coefficient as represented in the balanced chemical reaction.
k= rate constant
a= order with respect to A
b = order with respect to B
Answer:
A) 100 mL
Explanation:
At constant temperature and number of moles, Using Boyle's law
Given ,
V₁ = 200 mL
V₂ = ?
P₁ = 60 kPa
P₂ = 120 kPa
Using above equation as:
