Predict the shift of equilibrium for each of the folloing conditions...?

Question

Predict the shift of equilibrium for each of the following conditions in the following reaction involving gaseous reactants and products.


ok i have no idea how to write a subscrpit on the computer soo if a nuber comes AFTER the letter then its a subscrpit

N2+3H2 *arrows going back n forth* 2NH3 + heat

a) NH3 is added to the reaction.

b) NH3 is removed from the reaction

c) the pressure is increased

d) the temperature is decreased.


thankx

Answer 1

Le Chatelier's Principle: The equilibrium system responds to a change in a way that will counteract the change.

a) response: get rid of NH3, by converting it back to N2 and H2 (shift to reactants)

b) response: make more NH3, by converting N2 and H2 to NH3 (shift to products)

c) response: derease pressure by reducing numbers of moles of molecules; convert N2 and H2 to NH3 (shift to products)

d) response: produce more heat; reaction is exothermic, so producing more NH3 will also produce more heat (shift to products)

(I can't do subscripts either)
