Which of the following gases would have the greatest kinetic energy at 300 K?
1 answer:
Answer:
D. All of them would have the same kinetic energy
Explanation:
The expression for the kinetic energy of the gas is:-
k is Boltzmann's constant =
T is the temperature
<u>Since, kinetic energy depends only on the temperature. Thus, at same temperature, at 300 K, all the gases which are will posses same value of kinetic energy.</u>

Answer : The order of reaction with respect to A is, first order reaction.
The order of reaction with respect to B is, zero order reaction.
The overall order of reaction is, first order reaction.
Explanation :
Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
For the given chemical equation:
Rate law expression for the reaction:
where,
a = order with respect to A
b = order with respect to B
Expression for rate law for first observation:
....(1)
Expression for rate law for second observation:
....(2)
Expression for rate law for third observation:
....(3)
Dividing 1 from 2, we get:
Dividing 1 from 3, we get:
Thus, the rate law becomes:
Thus,
The order of reaction with respect to A is, first order reaction.
The order of reaction with respect to B is, zero order reaction.
The overall order of reaction is, first order reaction.
