Hello, thank you for this informative video! For the reaction written below, H2 + Cl2 --> 2HCl, which way would the equilibrium shift if pressure was increased? Or would it change at all, since they both have 2 moles on each side.

@OldSchoolChemistry

Жыл бұрын

Hi Yeorimpark, you are correct! If you have the same number of gas moles on the reactant and product sides of the reaction, there is no shift in equilibrium with a change of pressure or volume. Thanks! :)

Then you have two impacts at once. Consider both. It takes advanced knowledge and math to predict the shift if you change both temperature and pressure.

Will there be a change in equilibrium if you add a catalyst?

@OldSchoolChemistry

Жыл бұрын

No:) The reaction will achieve equilibrium faster but equilibrium does not shift. Great question!

Thank you very much for this Ma'am, It was very helpful. I had a question that if we introduce an inert gas during the reaction, do we take the change in pressure in that case as well??

@OldSchoolChemistry

Hi Prachisharma, here is a great explanation from Chemistry Libre Texts: Add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: This will increase the total pressure of the system, but will have no effect on the equilibrium condition. That is, there will be no effect on the concentrations or the partial pressures of reactants or products. Thanks!

Sorry am dumb ,but how do you know how many moles each side have ?

@OldSchoolChemistry

Hi Herrera Herrera, that is not a dumb question. It is a great question! You add the molar coefficients (those are the large numbers in front of the compounds) on the reactants side and product side. For example every species in this chemical equation is a gas: 1 N2 + 3 O2 -> 2 NH3. There are 2 moles on the product side and 4 moles on the reactants side. I hope that helps!
