Ammonium dichromate upon heating decomposes to give nitrogen gas and chromium oxide is it a redox reaction ?
If so what is the type of the redox whether inter or introamolecular

Explanation

To determine whether the decomposition of ammonium dichromate is a redox reaction and to classify it as inter or intra-molecular, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reaction**:
The decomposition of ammonium dichromate can be represented as:
\[
(NH_4)_2Cr_2O_7 \xrightarrow{\text{heat}} N_2 + Cr_2O_3 + H_2O
