Question

1. For the reaction 3 CIO - (aq) → CIO, - (aq) + 2Cl(aq) doubling the concentration of CIOquadruples the initial rate of formation of CIO:: What is the rate expression for the reaction? is first order in CsH5N_CI 2. The reaction CoHsN2Cl(aq) + H2O(l) → CH5OH(aq) + N2 (g) + HCl(aq) and zero order in H2O. What is the rate expression? 3. For the reaction 2 NO(g) + Cl2(g) → 2 NOCI (g) If the concentration of NO is tripled, the rate of the reaction increases by a factor of nine. If the concentration of Cl, is cut in half, the rate of the reaction is decreased to half the original rate. Find the order of reaction for each reactant and write the rate expression for the reaction. 4. A reaction has the experimental rate law of Rate = k[A]?. a) What happens to the rate if the concentration of A is tripled? b) What happens to the rate if the concentration if A is reduced to one third the initial concentration? 5. The reaction 2 NO2 (g) + 0; (g) → N2Os (s) + O2(g) is first order with respect to each reactant. a) Write the rate expression for the reaction b) How does doubling the concentra

Answer 1

the Reaction Step1 In 340.199) -> 403 (aq)+24 laq). Rate law is the relationship between rate of reaction to the late Constant and the concentration of reactants raised to some powers. 10, (1) Rate = K[ 40- - because here stoichiometry of qož is 3. Stipa :- According to Question double concentration of clo quadruples initial rate of formation of 403. to, 4X & ato (1')= K[240-33 4xx' = 2K [40- 1. From equation He'=qk

2 Cols N₂4 (aq) + H₂0 (1) - GHS OH | aq) + H2(I) + HU(aq). Bote= K[CHş N2 47' [H2 07 ° According to Colls N₂ 4 Question - First I use so, order 1. H₂o - zaw older use O. and [H₂o] = 1 so rate = k[ Co HS Ne 4] where K= lale Constant.
