Complete the following problems in your Homework Journal to be collected in class Use lecture notes assigned readings and your own resourcefulness (e g do some research it necessary on -1.n degree , in the library, or talking with each other - no outright copying. though!) to help your learning Answer the following questions about reaction rates Manganate ions. MnO_4 ^2-, react at 2.0 mol^-1 min^-1 in acidic solution to form permanganate ions and manganese(IV) oncle according to the equation MnO_4^2-(aq) + 4 H'(aq) right arrow 2 MnO_4(aq) + MnO_2(s) + 2 H_2O(l) What is the rate of formation of permanganate ions What is the rate of reaction of Hl(aq) If possible. write the rate law for the reaction If not, explain why not, Consider the graph of the concentration of a substance over time Is times a reactant or product of the reaction' Is the reaction speeding up Mowing down or not changing its rate as time progresses, Why is the average rate of the reaction different between points I and 2 than between points 2 and 3 (basic -competency) Answer the following questions about reaction rates and rate laws Consider the following general reaction and data 2A + 2B + C right arrow D + 3E Write the rate law for this reaction. Calculate Ole rate constant Write a mathematical expression that relates the rates of consumption of reactants to the rates of formation 01 products for this reactionExplanation / Answer
Post one more question to get the remaining answers since the question contains lot of sub-parts
Q1)
a)
(i) 3 moles of manganate ions yield 2 moles of permanganate ions
Rate of formation = 2/3 * 2 mol-L^(-1) min^(-1) = 4/3 mol-L^(-1) min^(-1)
(ii) 3 moles of manganate react with 4 moles of H+ ions
Rate of reaction of H+ = 4/3 * 2 mol-L^(-1) min^(-1) = 8/3 mol-L^(-1) min^(-1)
(iii) The exact dependence of each reactant and product is not known, hence the rate law of the reaction can't be written for this equation
b)
(i) X is a product since it's concentration is increasing with the time
(ii) The slope of the curve is higher from 1-2 as compared to 2-3, hence the reaction is occuring at slower rate from the original start of the reaction
