Practice HPCET Rate Constant in the app →The **rate constant** $k$ in a rate law equals the rate of reaction when:For a zero-order reaction, the units of the rate constant $k$ are:For a first-order reaction, the units of the rate constant $k$ are:For the reaction $2\text{NOBr}(g) \to 2\text{NO}_2(g) + \text{Br}_2(g)$, rate = $k[\text{NOBr}]^2$. If rate = If rate = $k[A][B]^2$, what are the units of $k$?For the reaction $2A + B \to 2C + D$, rate = $6 \times 10^{-4}$ mol dm⁻³ s⁻¹ at $[A] = [B] = 0.3$ M. If the reFor the reaction A + B → P with $\text{rate} = k[A][B]^2$, rate = $3.6 \times 10^{-2}$ mol dm⁻³ s⁻¹ when [A] =
