The equilibrium constant value for the reaction between N 2 and O 2 , placed in a flask at an initial pressure of 0.80 and 0.20 atm , is given. The partial pressure of NO is to be calculated. Concept introduction: The state when the reactants involved in a chemical reaction and the products formed in the reaction exist in concentrations having no further tendency to change is known as an equilibrium state of the reaction. When the equilibrium constant is expressed in terms of pressure, it is represented as K p . To determine: The partial pressure of NO .

Interpretation Introduction
Interpretation: The equilibrium constant value for the reaction between
N2 and
O2, placed in a flask at an initial pressure of
0.80 and
0.20atm, is given. The partial pressure of
NO is to be calculated.

In the solid state, oxalic acid occurs as
a dihydrate with the formula H2C2O4
C+2H2O. Use this formula to
calculate the formula weight of oxalic
acid. Use the calculated formula
weight and the number of moles
(0.00504mol)
of oxalic acid in each titrated
unknown sample recorded in Table
6.4 to calculate the number of grams
of pure oxalic acid dihydrate
contained in each titrated unknown
sample.
