JEE Main 2019 Chemistry question
NO required for a reaction is produced by the decomposition of NO in CCl as per the equation, 2NO(g) → 4NO(g) + O(g). The initial concentration of NO is 3.00 mol L and it is 2.75 mol L after 30 minutes. The rate of formation of NO is:
Answer: (D)
Solution
−Δ[NO]/Δt = 0.25/30; rate of NO formation = 2 × that.
