Explain the problem surrounding the ammonia-making process in terms of chemical equilibrium.

bazaltina [42]

Answer is: at lower temperatures the reaction rate would decrease.

The lower is the temperature, the slower the reaction becomes.

The Haber process is procedure for the production of ammonia, in this process atmospheric nitrogen (N₂) is converted to ammonia (NH₃):

N₂ + 3H₂ ⇄ 2NH₃ ΔrH = -92 kJ/mol.

Because this is exothermic reaction (enthalpy is less than zero), at lower temperatures, the equilibrium is in favor of ammonia, but the reaction doesn't proceed at a detectable rate.

Compare (a) the number of drops and (b) the length of time, in minutes, required to deliver 50 mL of intravenous solutions when

Marina CMI [18]

Explanation:

Volume of intravenous solution to be delivered = 50 mL

1) Rate of drops per milliliter of the solution = r = 60 drops/mL

Number of drops delivered :

$60 drops/mL\times 50 mL = 3000 drops$

Time required to deliver 3000 drops = t

Rate of drop solution with respect to time = R = 1 drop/second

$\frac{3000 drop}{t}=1 drop/s$

t = 3000 seconds = 50 minutes (1 min = 60 seconds)

Number of drops delivered 3000.

50 minutes are required to deliver 50 mL of intravenous solutions.

2) Rate of drops per milliliter of the solution = r = 15 drops/mL

Number of drops delivered :

$15 drops/mL\times 50 mL = 750 drops$

Time required to deliver 750 drops = t

Rate of drop solution with respect to time = R = 1 drop/second

$\frac{750 drop}{t}=1 drop/s$

t = 750 seconds = 12.5 minutes (1 min = 60 seconds)

Number of drops delivered 750 .

12.5 minutes are required to deliver 50 mL of intravenous solutions.
