To perform a chi square test in catalysis, follow these steps: 1. Define the null hypothesis (H0) and alternative hypothesis (H1). 2. Collect the observed data from experiments. 3. Calculate the expected data based on theoretical models or previous experiments. 4. Use the chi square formula: χ² = Σ((O - E)² / E), where O is the observed frequency and E is the expected frequency. 5. Compare the calculated chi square value with the critical value from chi square distribution tables at a chosen significance level.
