Pressure and Moles

[Sophia Dinh 1D]

When counting moles for which way the equilibrium shifts, do you just count the coefficients or do you need to multiply that with the subscripts as well?

[Amanda Lin 2I]

You just count the coefficients to determine the equilibrium shift.

[KnarGeghamyan1B]

Add up the coefficients of the products, add up the coefficients of the reactants, then subtract to find the total change in moles for your equation.

[Abhi Vempati 2H]

Count the moles of gas on each side by counting the coefficients, which will help you determine the correct way equilibrium shifts.

[kim 2I]

Just the coefficients are counted for the number of moles. When pressure is increased, the equilibrium shifts to the side where there are less moles.

[Jesalynne 2F]

In order to see which way the reaction will shift you would count the coefficients.

[John Liang 2I]

You would only regard the coefficients because they represent the amt of whole molecules. the subscripts only show how many atoms there are in each molecule. you can think of the subscripts as too small to shift while the coefficients are.

[Vinita Saxena 2I]

Just count the coefficients since the subscripts are part of the molecule, not separate molecules.
