Answer:
a. 0.0022 M/s
b. 0.0011 M/s
Explanation:
Let's consider the following reaction.
2 NO(g) + O₂(g) → 2 NO₂(g)
The rate of disappearance of NO is 0.0022 mol NO. L⁻¹.s⁻¹
<em>a. At what rate is NO₂ being formed?</em>
The molar ratio of NO to NO₂ is 2:2. The rate of formation of NO₂ is:
<em>b. At what rate is molecular oxygen reacting?</em>
The molar ratio of NO to O₂ is 2:1. The rate of disappearance of O₂ is:
Answer:
Explanation:
Hello,
In this case, given the balanced reaction:
We can see a 2:4 mole ration between permanganate ion (118.9 g/mol) and manganese (IV) oxide (86.9 g/mol), that is why the resulting mas of this last one turns out:
