### Reaction Kinetics Example

Consider this reaction:

\[ 2Cl_2O_5 (g) \rightarrow 2Cl_2 (g) + 5O_2 (g) \]

At a certain temperature, it obeys this rate law:

\[ \text{rate} = \left(0.00575 \text{ M}^{-1} \cdot \text{s}^{-1} \right) [Cl_2O_5]^2 \]

**Problem:**

Suppose a vessel contains \( Cl_2O_5 \) at a concentration of \( 0.900\,M \). Calculate the concentration of \( Cl_2O_5 \) in the vessel 580 seconds later. You may assume no other reaction is important.

*Round your answer to 2 significant digits.*

**Answer Box:**

\[ \boxed{\phantom{M}} M \]

You should use the integrated rate law for a second-order reaction to find the concentration after a given time. The general form of the integrated rate law for a second-order reaction is:

\[ \frac{1}{[A]_t} = \frac{1}{[A]_0} + kt \]

where:
- \( [A]_t \) is the concentration of \( A \) at time \( t \)
- \( [A]_0 \) is the initial concentration of \( A \)
- \( k \) is the rate constant
- \( t \) is the time

Given:
- \( [Cl_2O_5]_0 = 0.900 \, M \)
- \( k = 0.00575 \, \text{M}^{-1} \cdot \text{s}^{-1} \)
- \( t = 580 \, \text{s} \)

Calculation:
\[ \frac{1}{[Cl_2O_5]_t} = \frac{1}{0.900 \, M} + (0.00575 \, \text{M}^{-1} \cdot \text{s}^{-1})(580 \, \text{s}) \]

\[ \frac{1}{[Cl_2O_5]_t} = 1.111 + 3.335 = 4.446 \]

\[ [Cl_2O_5]_t = \frac{1}{4.446} \
