1.00 mol of A and 1.00 mol of B are placed in a 4.00-L
container. After equilibrium is established, 0.400 mol of D is
present in the container. Calculate the equilibrium constant for

In the reaction below, 4.24 atm each of H2 and I2 were placed
into a 1.00 L flask and allowed to react: H2(g) + I2(g) <=> 2

A 4.10 −g sample of a mixture of CaO and BaO is placed in a
1.00-L vessel containing CO2 gas at a pressure of 735 torr and a
temperature of 26 ∘C. The CO2 reacts with the CaO and BaO, forming
CaCO3 and BaCO3. When the reaction is complete, the pressure of the
remaining CO2 is 155 torr .
Calculate the number of moles of CO2 that have reacted.
Calculate the mass percentage of CaO in the mixture.
If 1.00 mol of argon is placed in a 0.500-L container at 19.0 ∘C
, what is the difference between the ideal pressure (as predicted
by the ideal gas law) and the real pressure (as predicted by the
van der Waals equation)? For argon, a=1.345(L2⋅atm)/mol2 and
b=0.03219L/mol.
When 0.127 mol of NO and 17.80
g of bromine are placed in a 1.00-L reaction vessel and sealed, the
mixture is heated to 350 K and the following equilibrium is
established:
2NO(g) + Br2(g) ------> 2NOBr(g)
If the equilibrium concentration of nitrosyl bromide is
8.63X10^-2 M, what is Kc ?
4.60 mol of solid A was placed in a sealed 1.00-L container and
allowed to decompose into gaseous B and C. The concentration of B
steadily increased until it reached 1.10 M, where it remained
constant.
A(s) <===> B(g) + C(g)
Then, the container volume was doubled and equilibrium was
re-established. How many moles of A remain?
