Question 1 1 pts Which of the following best defines reaction rate in terms of O3 for the following reaction? 203(g) → 302(g) Rection Rate - -2 A0J] Rection Rate = Δ[O3] ΔΙ Rection Rate - Rection Rate = Rection Rate - 03 Question 2 1 pts In the hydrogen fuel cell, H2 and O2 gases react to form liquid H2O. Write a balanced equation for this reaction and then determine which of the following statements is true. O The rate of disappearance of O2 is 4 times the rate of disappearance of H2 O The rate of disappearance of H2 is 4 times the rate of disappearance of O2 O The rate of disappearance of O2 is equal to the rate of disappearance of H2 O The rate of disappearance of H2 is 2 times the rate of disappearance of O2 O The rate of disappearance of O2 is 2 times the rate of disappearance of H2Question 5 1 pts The data in the table below shows the values of the initial concentrations and the initial reaction rate for each experiment for the following reaction: A(aq) + B(aq) → C(aq) + D(aq) + E() Use the data provided to determine the rate law for the reaction. Experiment # | [A]o (M) [B]o (M) 0.0300 0.0300 0.0598 Initial Rate (M/s) 0.160 4.00 x 10 -3 2 0.0200 5.00 × 10 -3 3 0.0200 5.00 × 10 2 O O O Rate= MA] Rate=k[A] Rate-KB]2 Rate = 서B] Rate = MA][B] O 2Given the graphed data for a given reaction, which of the following statements best describes the order of the reaction with respect to reaction species A, and is A a reactant or a product? In[ 5 1/[A] vs time Al vs time 0.20--[A] vs time -2.0 In[Al 3.0 40 0.15 IA] k slope -4.0 0.05 0.00 5.0 Tme sec. Time sec Time se O 3rd order in A; A is a reactant 3rd order in A; A is a product O 1st order in A; A is a product O 2nd order in A; A is a product O 1st order in A; A is a reactant O 2nd order in A, A is a reactant Question 9 1 pts The rate constant for a particular reaction that is 1st-order in N205s 0.525 min. How much time will it take for the concentration of N205 to decrease to one-third its initial concentration? Make sure you pick an answer with the correct units (HInt: For a 1st-order reaction, the amount of time it takes to reduce a reactants concentration to one-third is independent of the initial concentration of reactant.) O 2.09 hr 1.32 min O 1.32 hr 1.74 sec O 1.74 min O 2.09 minQuestion 10 1 pts The half-life (t1/2) for a chemical reaction is the time it takes for the concentration of reactant to decrease to one-half its initial concentration. For a first-order reaction, the half-life is a constant at a given temperature. So the half-life is also the amount of time it takes for the concentration to change from one-half to one-fourth, and from one-fourth to one-eighth, etc. If the half-life for a first-order reaction is 12.0 minutes, what percentage of reactant remains unreacted after 48.0 minutes? O 12.5% O 25.0% O 50,0% O 6.25% O 30.000
