The reaction A + B → C is found to have the rate law: rate = k[A][B]. When the concentrations of A and B are both 0.100 M, the reaction rate is 0.250 M/s. What is the numerical value of k for this reaction (with appropriate units where time is in seconds and concentration is in M, as needed). 0.0025 0.0400 400. 2.5 25.0
The reaction B ➔ products follows the rate law Rate = k [B]2. If the initial concentration of B is 0.400 M, it requires 100 seconds for [B] to fall to 0.200 M. The additional reaction time (in seconds) that is required for [B] to reach 0.100 M is A. 125 B. 175 C. 100 D. 150 E. 200

Match the descriptions to the appropriate term. Rate of reaction Rate law Rate constant Answer Bank always has units of amount per time (i.e., molarity per second, M/s, or molarity per minute, M/min) symbolized as k can have different units, such as molarity per second (M/s), inverse seconds (s-1), or inverse molarity-seconds (M-1.s-1 depending on the reaction order a formula that relates reactant concentration to reaction rate
The rate law for the reaction 2NO2 + O3 → N2O5 + O2 is rate = k[NO2][O3]. Which one of the following mechanisms is consistent with this rate law? A) NO2 + NO2 → N2O4 (fast) N2O4 + O3 → N2O5 + O2 (slow) B) NO2 + O3 → NO5 (fast) NO5 + NO5 → N2O5 + 5/2O2 (slow) C) NO2 + O3 → NO3 + O2 (slow) NO3 + NO2 → N2O5 (fast) D) NO2 + NO2 → N2O2...
Iwo experiments were performed to determine the rate law for the reaction shown below. In both experiments [A] was measured as a function of time in seconds; in experiment 1, 0.200 M B was used and in experiment 2, 0.400 M B was used. In both experiments, the graph of [A] vs time was linear; the slopes of those lines are given in the table. 4. A+B AB Exp Initial [B] (M) Slope of [A] vs time 1 -0.00354 0.200...
