The use of dynamic inert atmosphere in thermogravimetric analysis (TGA):
(a)decreases decomposition temperature
(b)decrease weight loss
(c)reduces rate of decomposition
(d)increases weight loss
Answer
Answer: A ✓ checked by 4AB · confidence medium
The source book printed D; on checking, A is correct — see the explanation.
Explanation
A flowing (dynamic) inert gas sweeps away the gaseous products, shifting the decomposition equilibrium forward so decomposition starts at a lower temperature (a); the total mass loss is unchanged.
