Which of the following represents the rate at which ClO₂⁻(aq) is appearing in the reaction below? 2 ClO₂(aq) + 2 OH⁻(aq) → ClO₂⁻(aq) + ClO₃⁻(aq) + H₂O(l)

In a certain chemical reaction, substance A combines with substance B to form substance Y. At the start of the reaction, the quantity of A present is a grams, and the quantity of B present is b grams. Assume a < b and y ≤ a. At time t seconds after the start of the reaction, the quantity of Y present is y grams. For certain types of reactions, the rate of the reaction, in grams/sec, is given by Rate = k(a - y)(b − y), - where k is a positive constant. 1. Sketch a graph of the rate against y. For what values of y is the rate nonnegative? Give your answer as a union of intervals, e.g., (- infinity,-a] U (a, 2b) YE 2. Use your graph to find the value of y at which the rate of the reaction is fastest. У =

Consider the chemical reaction: H2SO4(aq) +2 NaOH(aq) → 2 H2O(l) + Na2SO4(aq) If the sulphuric acid is reacting at a rate of 1.60 mol/L•s, the sodium hydroxide will react at a rate of

A reaction between substances A and B has been found to give the following data: 3A +2B 2C+D Al (mol/L) (mol/Rate of appearance of C 10 x 102 10 x 102 30 2.0 x 102 30 mol / L-hr) 0.300 x 100 810x 10 3 24 x 10-5 1.20 x 10-8 30 x 10-5 10 0 x 102 1.0 3.0 x 10- Using the above data, determine: a) the order of the reaction with respect to A and B - b) the rate law, and - c) calculate the specific rate constant
