Given the following balanced equation, determine the rate of reaction with respect to [02]. If the rate of O2 loss is 2.64 x 10-3 M/s, what is the rate of formation of SO3?
2 SO2(g) + O2/g) -→ 2 503(g)

Which statement is true about a catalyst? a: a catalyst decreases the rate of the reaction. b. a catalyst is consumed during a chemical reaction. c. a catalyst lowers the activation energy of a reaction. d. a catalyst increases the reactant concentration during a reaction.
