I think the answer is number 3
Just because they have same atomic masses doesn’t make them similar. They have different chemical properties because they are made of different things. And physical properties because they form different bonds with different atoms in the process.
Answer:
92.0 torr/min.
Explanation:
- For the reaction: <em>2NO(g) + Cl₂(g) → 2NOCl(g).</em>
∵ The rate of the reaction = - 1/2(ΔP)NO/Δt = - (ΔP)Cl₂/Δt = 1/2(ΔP)NOCl/Δt.
∵ (ΔP)NO/Δt = - 184 torr/min.
<em>∴ The rate of change of the total pressure in the vessel = - 1/2(ΔP)NO/Δt</em> = (- 1/2)(- 184 torr/min) = <em>92.0 torr/min.</em>
