Question
### Determining the Rate Law and Rate Constant for a Reaction

Some measurements of the initial rate of a certain reaction are given in the table below.

\[ \begin{array}{|c|c|c|}
\hline
[H_2] & [I_2] & \text{Initial Rate of Reaction} \\
\hline
0.890 M & 1.01 M & 8.00 \times 10^4 \, \text{M/s} \\
0.890 M & 1.87 M & 1.48 \times 10^5 \, \text{M/s} \\
2.62 M & 1.01 M & 2.36 \times 10^5 \, \text{M/s} \\
\hline
\end{array} \]

Use this information to write a rate law for this reaction and calculate the value of the rate constant \( k \).

Round your value for the rate constant to three significant digits. Also, be sure your answer has the correct unit symbol.

#### To Enter:
\[
\text{Rate law:} \quad \text{rate} = k [H_2]^a [I_2]^b
\]

\[
k = \text{(value with unit)}
\]
