Calculate the pressure, in atmospheres, of 2.06 moles of helium gas in a 10.0-L container at 21 ∘C.

When the volume and number of particles of a gas are constant which of the following is also constant

What is the relation between concentration of reactants and the rate of chemical reaction?

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
