LeChâtelier’s Principle
Consider the following reaction at equilibrium for which
DH = 16.3 kJ:
NO(g) + Br2(g) NOBr2(g)
How will the reaction respond to each
of the following changes? (a) Br2(g) is added to the flask. (b)
The reaction
mixture is heated, thereby increasing the temperature. (c)
The pressure of the flask is suddenly doubled. (d) A
catalyst is added to the flask.
(e) NOBr(g) is removed from the flask.
(f) N2(g) is added to the flask.
