Shown below is the formation reaction of ammonia. How does the catalyst used in the industrial production of ammonia affect the activation energies of the forward and reverse reactions?
N2+3H2⇌2NH3
activation energy decreased for the forward reaction, increased for the reverse reaction
activation energy increased for the forward reaction, decreased for the reverse reaction
activation energy decreased both the forward and reverse reactions
activation energy increased for both the forward and reverse reactions

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
