Consider the reaction hc2h3o2(aq) h2o(l) → h3o (aq) c2h3o2–(aq). Which species is the conjugate acid?a. C2h3o2-(aq)b. H2o(l)c. H
saul85 [17]

The species that is the conjugate acid is HC₂H₃O₂(aq). The correct option is d.

<h3>What are conjugate acid?</h3>

Conjugates acids are those acids which are made when an acid donates a proton to a base according to Bronsted Lowry theory.

In other words, we can say that it is an acid with hydrogen ion. An example is  water (base) reacting with an acid to form the hydronium ion (conjugate acid).

Thus, the correct option is d, HC₂H₃O₂(aq).

VashaNatasha [74]

The question is incomplete, complete question is :

In the Haber reaction, patented by German chemist Fritz Haber in 1908, dinitrogen gas combines with dihydrogen gas to produce gaseous ammonia. This reaction is now the first step taken to make most of the world's fertilizer. Suppose a chemical engineer studying a new catalyst for the Haber reaction finds that 348 liters per second of dinitrogen are consumed when the reaction is run at 205°C and 0.72 atm. Calculate the rate at which ammonia is being produced.

Answer:

The rate of production of ammonia is 217.08 grams per second.

Explanation:

N_2+3H_2\rightarrow 2NH_3

Volume of dinitrogen used in a second = 348 L

Temperature of the gas = T = 205°C = 205+273 K = 478 K

Pressure of the gas = P = 0.72 atm

Moles of dinitrogen = n

n=\frac{PV}{RT}=\frac{0.72 atm\times 348 L}{0.0821 atm L/mol K\times 478 K}=6.385 mol

According to reaction, 1 mole of dinitriogen gives 2 mole of ammonia.Then 6.385 moles of dinitrogen will give:

\frac{2}{1}\times 6.385 mol=12.769 mol

Mass of 12.769 moles of ammonia;

12.769 mol 17 g/mol = 217.08 g

217.08 grams of ammonia is produced per second.So, the rate of production of ammonia is 217.08 grams per second.
