one of the most important chemical reactions is the haber process, in which n2 and h2 are converted to ammonia which is used in the production of fertilizers. consider that you have just produced 170 g of nh3 in a 50.0 l tank at 400.0 c. what was the total pressure of the gases that reacted to produce this ammonia?



Answer :

The total pressure of the gases involved in the reaction that created this ammonia was 22.0 atm. The haber process, in which n2 and h2 are transformed into ammonia, is one of the most significant processes.

Take into account the following balanced equation.

N2(g) + 3 H2(g) = 2 NH3 (l)

According to the equation, 1 mol of N2 will result in the production of 34.0 g of NH3. According to the equation for a balanced system, 3 moles of H2 create 34.0 g of NH3 for every 170 g of ammonia NH3. to make 170 g of NH3.

Prior to the reaction, there were a total of 20.0 mol (5.00 mol + 15.0 mol) gaseous moles.

The ideal gas equation can be used to get the pressure (P).

P.V = n.R.T

where V stands for volume (50.0 L)

There are n moles in a sample (20.0 mol)

The ideal gas constant, or R, is 0.08206 atm.L/mol.K.

The absolute temperature is T, which is 400.0 + 273.15 = 673.2K.

pressure is equal to n*R*T/v = 20*(0.08206*673.2)/50.0 = 22.0 atm.
