Answer to Question #189920 in General Chemistry for ganst

Question

How will the following conditions affect the equilibrium of the chemical reaction below: 

4NO_(g) + 6H₂O_(g) → 4NH₃ + 5O₂ ∆H = 904.4 kJ

a. adding more H₂O

b. removing O₂

c. increasing the temperature of the system

d. decreasing the pressure of the system

Answer 1

a) Increase[H2O]

add product, shift left, [NO] decreases.

b) Decrease [O2]

remove reactant, shift left, [NO] decreases.

c) Increase temperature

exothermic, temperature goes up, shift left, [NO] decrease.

d) Decreasing Pressure

exothermic, temperature goes down , shift right , [NO] increases.
