Answer:
Explanation:
The given reaction is :-
According to the law of mass action:-
The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.
Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.
The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.
m = 2 = is order with respect to
n = order with respect to H+
overall order = m+n = 3
n = 3 - m = 3 - 2 = 1
Rate law is:-
Given that the volume of cylinder at STP = 11.2 L
Standard temperature = 273 K
Standard pressure = 1 atm
Calculating the volume of gas at 202.6 kPa and 300. K:
Applying the combined gas law,
=
Plugging in the values and calculating final volume:
Therefore the correct answer will be, b) 6.15 L
