Thanks!!!

The following equilibrium partial pressures were measured at some temperature: Determine the value of the equilibrium constant at the temperature of the reaction for the following reaction. Your are given values to 3 significant figures, so make sure you answer to three significant figures to avoid rounding errors in Web Assign. In a different experiment at the same temperature, the equilibrium pressure of N2 was found to be 0.330atm and that of H2 to be 0.180 atm. What is the equilibrium pressure NH3 if K = 8.500 for the above reaction at the temperature of the equilibrium?

Explanation / Answer

2 NH3 <=> N2 + 3 H2

K = P(N2)P(H2)^3/P(NH3)^2


P(NH3) = (P(N2)P(H2)^3)/K)^(1/2)

= (0.330 x 0.180^3/8.500)^(1/2)

= 0.01505 atm (approximately 0.0150 atm)
