Generic 3 - Answer All Question

How does oxygen exchanges between maternal and fetal blood in a pregnant woman?

Oxidation of nitrogen monoxide was studied at 200^o C with initial pressures of 1 atm NO and 1 atm of O₂. At equilibrium partial pressure of oxygen is found to be 0.52 atm calculate K_P value.

The reaction CO(g) + 3H₂(g) u21cc CH₄(g) + H₂O(g) is at equilibrium at 1300 K in a 1K flask. It also contain 0.30 mol of CO, 0.10 mol of H₂ and 0.02 mol of H₂O and an unknown amount of CH₄ in the flask. Determine the concentration of CH₄ in the mixture. The equilibrium constant, K_c for the reaction at the given temperature is 3.90.

Write the value of K_P, and K_C equation for CaCO₃(s) u21ccCaO(s) + CO₂(g)

What is the effect of:
(i) addition of H₂
(ii) addition of CH₃OH
(iii) removal of CO
(iv) removal of CH₃0H
On the equilibrium 2H₂(g) + CO(g) u21cc CH₃OH(g)

Illustrate the formation of solid-vapour equilibrium with suitable example

Consider the reaction, N₂(g) + 3H₂(g) u21cc 2NH₃(g). Explain the effect of pressure on this equilibrium reaction.

Given the equilibrium
N₂O₄(g) u21cc 2NO₂(g) with K_p = 0.15 atm at 298 K
(a) What is K, using pressure in torr?
(b) What is K_C using units of moles per litre.

What inferences do you observe by the values of Q and K_c?

Discuss the changes you observe in the reaction of I synthesis of ammonia with preference to effect of pressure.
