Answer: Oxygen is the limiting reagent.
Explanation:
As can be seen from the given balanced equation:
3 moles of reacts with 1 mole of
1.52 moles of reacts with=
of
Thus is the limiting reagent as it limits the formation of products. (0.91-0.51)= 0.40 moles of
will remain as such and thus
is an excess reagent.
Answer:
The order of reaction is 2.
Rate constant is 0.0328 (M s)⁻¹
Explanation:
The rate of a reaction is inversely proportional to the time taken for the reaction.
As we are decreasing the concentration of the reactant the half life is increasing.
a) For zero order reaction: the half life is directly proportional to initial concentration of reactant
b) for first order reaction: the half life is independent of the initial concentration.
c) higher order reaction: The relation between half life and rate of reaction is:
Rate =
Half life =
where n = order of reaction
Putting values
Hence n = 2
Putting values
K = 0.0328
