D. For either thermal combination redox reaction or thermal decomposition redox reaction.

Answer

To determine the type of reaction represented by the equation \( \text{CO} + \text{I}_2\text{O}_5 \rightarrow \text{CO}_2 + \text{I}_2 \), we can follow these steps:

### Step 1: Identify the Reactants and Products
The reactants in this reaction are carbon monoxide (CO) and iodine pentoxide (I₂O₅). The products are carbon dioxide (CO₂) and iodine (I₂).

### Step 2: Assign Oxidation States
Next, we need to assign oxidation states to each element in the reactants and products:
- For CO:
- Carbon (C) in CO has an oxidation state of +2 (since O is -2).
- For I₂O₅:
- Iodine (I) has an oxidation state of +5 (calculated as 2X + 5(-2) = 0, thus X = +5).
- Oxygen (O) has an oxidation state of -2.
- For CO₂:
- Carbon (C) in CO₂ has an oxidation state of +4 (since O is -2).
- For I₂:
- Iodine (I) in I₂ has an oxidation state of 0 (elemental state).

### Step 3: Determine Changes in Oxidation States
Now we analyze the changes in oxidation states:
- Carbon (C) changes from +2 in CO to +4 in CO₂ (oxidation).
- Iodine (I) changes from +5 in I₂O₅ to 0 in I₂ (reduction).

### Step 4: Classify the Reaction
Since we have one species being oxidized (C) and another being reduced (I), this reaction is classified as a redox (reduction-oxidation) reaction.

### Step 5: Identify the Type of Redox Reaction
In this case, since two different reactant molecules (CO and I₂O₅) are involved in the redox process, it is classified as an intermolecular redox reaction. This is distinct from disproportionation or comproportionation reactions, where a single species is oxidized and reduced or where a single species is present in two different oxidation states, respectively.

### Conclusion
The reaction \( \text{CO} + \text{I}_2\text{O}_5 \rightarrow \text{CO}_2 + \text{I}_2 \) is an intermolecular redox reaction.
