Answer:
0.406 M
Explanation:
Let's consider the following reaction.
2 Cl₂O₅(g) → 2 Cl₂(g) + 5 O₂(g)
This reaction follows first-order kinetics with a rate constant (k) of 0.184 s⁻¹.
We can calculate the concentration [Cl₂O₅] at a certain time using the following expression.
where,
- [Cl₂O₅]₀: initial concentration
