### Decomposition of Hydrogen Peroxide - Problem Solving

**Instructions:**
In addition to filling in the blanks below, show all of your work for this problem on paper for later upload. 

**Problem Statement:**
The decomposition of hydrogen peroxide (H₂O₂) to water and oxygen below 20.0 °C has a rate constant of \( 1.8 \times 10^{-5} \, \text{s}^{-1} \). 

**Steps to Solve:**
1. **Determine the Order of the Reaction:**
   - First, write down the order of the reaction based on the rate constant.

2. **Calculate the Time for Concentration Change:**
   - Next, determine how many hours it will take for the peroxide concentration to drop to 0.10 M from an initial value of 0.75 M.

**Blank Fields:**

**1. Enter the order of the reaction in the box below.**
