More of `SO_(3)` decompose at low temperature.

Explanation

To determine whether more of SO₃ decomposes at low temperature, we need to analyze the decomposition reaction and apply Le Chatelier's principle.

### Step-by-Step Solution:

1. **Write the Decomposition Reaction**:
The decomposition of sulfur trioxide (SO₃) can be represented as:
\[
2 \text{SO}_3(g) \rightleftharpoons 2 \text{SO}_2(g) + \text{O}_2(g)
