A bimolecular reaction typically takes twice as long as a unimolecular reaction. The answer is true
<h3>
How is activation energy related to temperature?</h3>
- Consider what must occur for ClNO2 to react with NO to understand why reactions have an activation energy.
- First and foremost, these two molecules must clash in order to organise the system.
- Not only must they be brought together, but they must also be kept in precisely the appropriate orientation relative to one other in order for the reaction to occur.
- Some energy must also be used in order to break the Cl-NO2 bond and allow the Cl-NO bond to form.

Ionic compound is formed by negative and positive ions, these ions form ionic bond
Answer:
1.2 M
Explanation:
Let's consider the following reversible reaction.
CuS(s) + O₂(g) ⇌ Cu(s) + SO₂(g)
To find the equilibrium concentration of O₂ we will use an ICE Chart. We will only consider gases and aqueous species since the activity of solids and liquids is 1.
CuS(s) + O₂(g) ⇌ Cu(s) + SO₂(g)
I 2.9 0
C -x +x
E 2.9-x x
The equilibrium constant (Kc) is:
The concentration of O₂ at equilibrium is:
[O₂] = 2.9 -x = 2.9 - 1.7 = 1.2 M
Answer:
0.075 M
Explanation:
5Fe²⁺(aq) + MnO₄⁻(aq) + 8H⁺(aq) → 5Fe³⁺(aq) + Mn²⁺(aq) + 4H₂O(ℓ)
Using the moles of Fe²⁺ that reacted, we can <em>calculate the reacting moles of MnO₄⁻</em>:
0.0450 mol Fe⁺² * = 0.0090 mol MnO₄⁻
Now we divide the moles of MnO₄⁻ by the volume in order to <u>calculate the molarity of the solution</u>, keeping in mind that 120.0 mL = 0.120 L.
0.0090 mol MnO₄⁻ / 0.120 L = 0.075 M
