The moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.
The balanced chemical equation for the decomposition of Ammonia has been:
<h3>Computation for moles of Hydrogen produced</h3>
From the balanced chemical equation, decomposition of 2 moles of ammonia produces, 3 moles of hydrogen and 1 mole, nitrogen.
The moles of hydrogen produced along with 0.0351 mol nitrogen has been:
Thus, the moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.

Heat capacity or thermal capacity is a physical property of a material object, defined as the amount of energy (in the form of heat) that must be added to (or removed from) the object in order to achieve a small change in its temperature, divided by the magnitude of that change.
Answer : The rate order of reaction is, second order reaction.
Explanation :
Rate of reaction : It is defined as the rate of change in concentration of reactant or product with respect to time.
Order of reaction : It is defined as the sum of the exponents or powers to which the molar concentration in the rate law equation are raised to express the observed rate of reaction.
As per question the reaction will be :
The given rate expression is,
From this expression we conclude that the power of concentration of reactant A and B are 1, 1.
The sum of power of concentration of reactant A and B = 1 + 1 = 2
That means it is a second order reaction.
Hence, the rate order of reaction is, second order reaction.
