AGº is -32.7 kJ/mol of N2 for the reaction N2 (g) + 3H2 (g) = 2NH3(g) This calculation was for the reaction under standard conditions—that is, with all gases present at a partial pressure of 1 atm and a temperature of 25°C. Calculate AG for the same reaction under the following nonstandard conditions: . PN2 = 2.00 atm, PH2 = 7.00 atm, PNH3 = 0.021 atm, . and T = 100°C.

Consider the following equilibrium N2(g) +3H2(g) 2NH3(g) ΔG--34. kJ Now suppose a reaction vessel is filled with 8.06 atm of nitrogen (N2) and 6.48 atm of ammonia (NH3) at 176. °C. Answer the following questions about this system: rise fall Under these conditions, will the pressure of N2 tend to rise or fall? Dio Is it possible to reverse this tendency by adding H? In other words, if you said the pressure of N2 will tend to rise, can that...
1. Ammonia synthesis reaction 3H2 (g)+N2 (g) = 2NH3(g) takes place in a reactor under constant temperature 673 K. The initial molar ratio between Hz and N2 is 3:1 (no NH, is present initially), and the reaction is allowed to reach equilibrium. (a) If the pressure is kept constant at 1000 kPa, the molar fraction of NH3 at equilibrium is 0.0385. Please calculate Kp. (b) Using Kp obtained from part (a), please calculate the pressure (still kept constant) of this...
