Analysis of a reaction mixture showed that it had the composition 0.411 mol/l n2, 0.541 mol/l h2, and 0.12 mol/l nh3 at 800 k, at which temperature kc = 0.278 for n2(g) + 3 h2(g) ⇀↽ 2 nh3(g). calculate the reaction quotient qc .

The reaction quotient = 0.221.

Explanation:

, equilibrium will move in forward direction

, equilibrium is attained

, equilibrium will move in backward direction

Now, according to question

Given:

of the reaction is 0.278 at 800 K

The reaction quotient = 0.221.

The value of which means that reaction is going in forward direction

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.

it has both hydrogen and oxygen
