Calculate the equilibrium composition for the reaction H2−− 1 2O2 −−)−−* H2O when the ratio of the number of moles of elemental hydrogen to elemental oxygen is unity. Perform this calculation at T = 2000 K and P = 1 atm.

the equilibrium composition Kp is 3471.01

Explanation:

Given;

H₂ + ½O₂ ↔ H₂O

Using Gibb's formula;

---------(i)

where;

ΔG(T) is change in Gibb's energy and it is given as;

= 1(-241,820 + 82,593 -9904 - 2000 x 264.571) - 1(0 + 61,400 - 8468 - 2000 x 188.297) - 0.5(0 + 67,881 -8682 - 2000 x 268.655)

= -698273 + 323662 + 239055.5

= -135,555.5 KJ

Substituting this value into equation (i)

Therefore, the equilibrium composition Kp is 3471.01

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
