Question
Consider the gas-phase decomposition of
NOBr:
2 NOBr(g) = 2 NO(g) + Br2(g)
When 0.0500 mol of NOBR is added to an
empty 2.50 L container and the reaction is
allowed to reach equilibrium at 300. K, the
total pressure in the flask is 0.588 atm. What
will the total pressure be if 0.0700 mol of NO
is then added to the reaction chamber and
the reaction is allowed to reach equilibrium at
300. K again?
(You will need to solve a cubic equation to
answer this question. If you search for "cubic
equation solver" you'll find a number of
online calculators. Feel free to use them, but
reference the site in your solution.)
