Identify the incorrect statement below concerning chemical kinetics: question 1 options: a) the rate law expresses how the rate varies with concentration of species. b) the rate of a chemical reaction is affected by the temperature of the reaction. c) the rate of a chemical reaction changes with time. d) the rate constant of a reaction changes when the reactant concentrations change. e) the rate law of a chemical reaction bears no relationship with the balancing coefficients of the overall reaction.

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
