Question

In general, which conditions a, b, c or d would you expect to give the fastest rate of reaction for the following reaction? Assume the reaction is not zero order in either reactant. Thoroughly explain your reasoning for your choice. AI(NO_3)_3 (aq) + 3 NaOH_(aq) rightarrow AI(OH)_3 (aq) + 3 NaNO_3_(aq) [AI(NO_3)_3] = 0.10M; [NaOH] = 0.10M; T = 15 degree C [AI(NO_3)_3] = 0.01M; [NaOH] = 0.10M; T = 35 degree C [AI(NO_3)_3] = 0.01M; [NaOH] = 0.010M; T = 65 degree C [AI(NO_3)_3]: 0.001M; [NaOH] = 0.10M; T = 85 degree C

Explanation / Answer

If zero order

then...

Ignore all concentrations, since Rate does NOT depends in concentration for ZERO Order

only

RAte = k

since K is dependant of Temperature

then

d > c > b > a

since increase in T increases Rate
