Based on the information provided, it tells us that the rate constant is 14 .5 and that it's first order with respect to both reactants, nitric acid and ammonia.

So that means we've got nitric acid, hno3, raise to the 1, and ammonia, nh3, raised to the 1, and ammonia, nh3, raised to the 1, we can then write the rate law as rate is equal to k multiplied by each of these concentrations raised to the first power.

So if we know the rate constant, which we do, 14 .5, 1 over molar seconds, we know the concentration of nitric acid as provided at 0 .050 molar, and ammonia at 0 .10 molar, we'll get, one of the molarities to cancel and we'll end up with units of molar per second, which are the units for rate, and we get 0 .0725, or we could round it to three...
