We’re being asked to calculate the units for the rate constant. We can calculate the rate constant of the reaction from its rate law.
Recall that the rate law only focuses on the reactant concentrations and has a general form of:
k = rate constant
A & B = reactants
x & y = reactant orders
Reaction: NH4+(aq) + NO2−(aq) → N2(g) + 2H2O(l)
NH4+(aq) + NO2−(aq) −→ N2(g) + 2H2O(l)
is first order in ammonium ion and first-order in nitrite ion. What are the units for the rate constant?
A. M s−1
B. M−1 s−1
E. M−2 s-1
