Answer:
The rate decreases as the concentration of the reactants decreases.
Explanation:
The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
During a reaction, the concentration of a reactant decreases exponentially with time while that of a product increases exponentially with time. This is because a reactant is consumed in a reaction while products builds in that same reaction.
The reaction rate therefore is directly proportional to the concentration of the reactants.
Number of moles : n₂ = 1.775 moles
<h3>Further explanation</h3>
Given
Moles = n₁ = 1.4
Volume = V₁=22.4 L
V₂=28.4 L
Required
Moles-n₂
Solution
Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
The ratio of gas volume will be equal to the ratio of gas moles
![\tt \dfrac{V_1}{V_2}=\dfrac{n_1}{n_2}](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7BV_1%7D%7BV_2%7D%3D%5Cdfrac%7Bn_1%7D%7Bn_2%7D)
Input the values :
n₂ = (V₂ x n₁)/V₁
n₂ = (28.4 x 1.4)/22.4
n₂ = 1.775 moles
