We're being asked to calculate the rate of change of oxygen gas if nitric oxide is found to be 1.10 M/min.
4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(l)
Recall that the average rate of a reaction is given by:
where Δ[A] = change in concentration of reactants or products (in mol/L or M) and Δtime = change in time. We can simply do a rate-to-rate comparison based on the stoichiometric coefficients.
Ammonia reacts with oxygen according to the equation: 4 NH3(g) + 5 O2(g) => 4 NO(g) + 6 H2O(l). In an experiment in which the rate of change of nitric oxide is found to be 1.10 M/min, what is the rate of change of oxygen gas?
A. 0.880 M/min
B. –0.880 M/min
C. –1.38 M/min
D. –0.220 M/min
E. –0.275 M/min
