(a)
Interpretation:
Whether the following reaction is in equilibrium or not has to be determined.
Concept Introduction:
The condition of equilibrium is a state of balance of processes that runs in opposite directions. At equilibrium, the formation of a product from the reactant balances the formation of reactant from the product. Also, the change in concentration of reaction and product seems to be negligible at the equilibrium state.
A reaction quotient
The general equilibrium reaction is as follows:
Here,
The expression of the reaction quotient for the above reaction is as follows:
Here,
The concentration of reactants and products changes in order to bring reaction quotient and equilibrium constant closer. Therefore, the direction of reaction can be predicted as follows:
(1) If
(2)If
(3)If
(b)
Interpretation:
If the following reaction is not at equilibrium then the direction of reaction has to be determined.

Compare the pressures given by (a) the ideal gas law, (b) the van der Waals equation, and (c) the Redlic-Kwong equation for propane at 400 K and p = 10.62 mol dm³. The van der Waals parameters for propane are a = 9.3919 dm6 bar mol-2 and b = 0.090494 dm³ mol−1. The Redlich-Kwong parameters are A = 183.02 dm bar mol-2 and B = 0.062723 dm³ mol-1. The experimental value is 400 bar.arrow_forwardResearch in surface science is carried out using stainless steel ultra-high vacuum chambers with pressures as low as 10-12 torr. How many molecules are there in a 1.00 cm3 volume at this pressure and at a temperature of 300 K? For comparison, calculate the number of molecules in a 1.00 cm3 volume at atmospheric pressure and room temperature. In outer space the pressure is approximately 1.3 x 10-11 Pa and the temperature is approximately 2.7 K (determined using the blackbody radiation of the universe). How many molecules would you expect find in 1.00 cm3 of outer space?arrow_forward
