Question

For the reaction: 3 Cu(s) + 8 HNO3(aq) → 3 Cu(NO3)2(aq) + 2 NO(g) + 4 H2O(l), the rate of change of HNO3 −Δ[HNO3]/Δt can be expressed equivalently as?

For the reaction: \[3 \text{Cu}(s) + 8 \text{HNO}_3(aq) \rightarrow 3 \text{Cu(NO}_3)_2(aq) + 2 \text{NO}(g) + 4 \text{H}_2\text{O}(l)\] The rate of change of \(\text{HNO}_3: -\Delta[\text{HNO}_3]/\Delta t\) can be expressed equivalently as: - **A)** \(-\Delta[\text{Cu}]/3\Delta t\) - **B)** \(8\Delta[\text{Cu}]/\Delta t\) - **C)** \(\Delta[\text{H}_2\text{O}]/2\Delta t\) - **D)** \(4\Delta[\text{NO}]/\Delta t\) Correct! - **E)** \(3\Delta[\text{Cu(NO}_3)_2]/\Delta t\) The correct choice is **D**: \(4\Delta[\text{NO}]/\Delta t\).
