reacto hour. What el from the reaction N,F 4 torr pend total pressure in the vessel l closed r 182 are the rates of change of NH, partial ange of Nu () is 2 NH(2) Laws (Section 14.3) te C obeys the following rate law: [A] is doubled, how will the rate changet 27 A reaction A + B- n Rate k[B] (a) If villthe rand B? What is the overall reaction order? (e) What t change? (b) What are the reaction or- are the units of the rate constant? K2s Consider a thetical reaction between A, B, and C that is reac in A, zero order in B, and second order in C. (a) first order Write the rate law for the reaction. (b) How does the rate e when [A] is doubled and the other reactant concentra tions are held constant? (c) How does the rate change when [B

Explanation / Answer

From the given reaction A+B ------> C

And from given rate law equation it is clear that the rate of the reaction depends only on concentrations of B and doesn't depend on concentrations of A.

a) Hence as we double the concentration of A it won't effect on rate of the reaction.

b) order of the reaction with respect to A = 0

Order of the reaction with respect to B = 2

Hence over all order of the reaction = 0+2= 2

Hence it's a second order reaction

c) Units of second order rate constant = M^-1s^-1 or M^-1 min^-1
