When of and of are reacted to form in a closed container: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
When $1 \text{ mole}$ of $N_2$ and $3 \text{ moles}$ of $H_2$ are reacted to form $NH_3$ in a closed container:
Answer: A,B,C,D
💡 Solution & Explanation
$N_2 + 3H_2 \rightarrow 2NH_3$. <br>Mass and Atoms are always conserved. <br>Moles of molecules: $4 \rightarrow 2$ (decreases). <br>Since $P \propto n$ (at constant T, V), the pressure drops as the number of molecules decreases.
