The rate law for the reaction $$\mathrm{NH}_{4}^{+}(a q)+\mathrm{NO}_{2}^{-}(a q) \longrightarrow \mathrm{N}_{2}(g)+2 \mathrm{H}_{2} \mathrm{O}(l)$$ is given by rate $=k\left[\mathrm{NH}_{4}^{+}\right]\left[\mathrm{NO}_{2}^{-}\right] .$ At $25^{\circ} \mathrm{C},$ the rate constant is $3.0 \times 10^{-4} / M \cdot$ s. Calculate the rate of the reaction at this temperature if $\left[\mathrm{NH}_{4}^{+}\right]=0.26 \mathrm{M}$ and $\left[\mathrm{NO}_{2}^{-}\right]=0.080 M$.

$$6.2 \times 10^{-6} \mathrm{M} / \mathrm{s}$$

In probability theory, the conditional probability of an event A given that another event B has occurred is defined as the probability of A given B, written as P(A|B). It is a function of the probability of B, the probability of A given B, and the probability of B.

In chemistry, kinetics is the study of the rates of chemical reactions. The rate of a reaction is the change in concentration of a reactant over time. The rate of reaction is dependent on the concentration of the reactants, temperature, and the activation energy of the reaction.

for this question were Abbas, you calculate the rate of a reaction so we're given the reaction of ammonium waas. Nitrogen dioxide yields di nitrogen in water soon to calculate the rate of this reaction, we're gonna look at the real law. So we're given the rate law so the rate is equal to a rate constant cake times the concentration of ammonium times, the concentration of nitrogen dioxide. The rest of this problem is pretty much just a plug in check problem. OK, so we're given a re constant K is equal to three times 10 to the negative fourth similarity her second. The concentration pandemonium is equal. Teoh zero point 26 Moller and our concentration of nitrogen dioxide is equal to zero. Wait zero 80 Mueller So now we're gonna take all these variables are cake illustration of ammonium in the concentration of nitrogen dioxide and plugged them into our rate equation. So a rate is going to be equal to Okay, so three kinds 10 to the negative fourth hilarity for a second times the concentration of ammonia. The times zero point 26 moller times are concentration of national now Exide zero white zero 80 Mueller. And if we multiply that out, we get six weight 24 times, 10 to the negative six. And our units are gonna be military her second.
