Question 1   1.5 / 1.5 pts Consider the reaction 5 Br − ( aq ) + Br O 3 − ( aq ) + 6 H + ( aq ) → 3 Br 2 ( aq ) + 3 H 2 O ( l ) The average rate of consumption of Br − is 1.86 M /s over the first two minutes . What is the average rate of formation of Br 2 during the same time interval ?
1.116
Question 2   1 / 1 pts Which of the following reactions have rates that depend on concentration of reactant A ?
Question 4   1 / 1 pts Observe the following reaction and explain why the reactants do not form the potential products . The reaction equation is : 2 ClO →O 2 + Cl 2
Question 5   1 / 1 pts Observe the following reaction and explain why the reactants do not form the potential products . The reaction equation is : 2 ClO → O 2 + Cl 2
Question 6   1 / 1 pts Which reaction is predicted to have a higher frequency factor ?
1 Reaction
1 : NO ( g ) + O ( g ) - > NO 2 ( g ) ( NO 2 has the structural formula ONO ) Reaction
2 : NO 2 ( g ) + NO 2 ( g ) -> N 2 O 4 ( g ) ( N 2 O 4 has the structural formula O 2 NNO 2 ) Reaction 1 because the reaction is more complex Correct ! Reaction 1 because the reaction is less complex Reaction 2 because the reaction is more complex Reaction 2 because the reaction is less complex
Question 1 1.5 / 1.5 pts Consider the reaction 5 Br (aq) + BrO 3 (aq) + 6 H + (aq) → 3 Br 2 (aq) + 3 H 2 O (l) The average rate of consumption of Br is 1.86 M/s over the first two minutes. What is the average rate of formation of Br 2 during the same time interval? Enter your answer numerically in units of M/s. Correct! Correct Answer 1.12 margin of error +/- 2%
Question 2 1 / 1 pts Which of the following reactions have rates that depend on concentration of reactant A?
Question 3 1 / 1 pts Observe the following reactions and predict if the reactants will react, assuming that they have sufficient energy. The reaction equation is: 2 ClO → O 2 + Cl 2
Select all that apply.
Question 4 1 / 1 pts Observe the following reaction and explain why the reactants do not form the potential products. The reaction equation is: 2 ClO→O 2 + Cl 2 Correct!
