Question
Consider this reaction: I_2(g)_460 K + Cl_2(9) 2 ICI(if) K = 6.91 times 10^3 at Calculate delta_r G for the reaction at 460 K under each of the following conditions: standard conditions Express your answer using three significant figures and include the appropriate units. at equilibrium Express your answer using three significant figures and include the appropriate units. P_I_2 = 0.325 bar P_CI_2 =0.101 bar P_ICI = 2.55 bar Express your answer using one decimal place and include the appropriate units.Explanation / Answer
Part A
We have the relation delta G0 = -2.303 RT log K
Given T= 460K and K = 6.91x105 and R= 8.314 J
substituting these values
delta G = -2.303 x 8.314 x 460 x log 6.91 x 105
= -51432.28 J
= -51.432 kJ
Part C
We know Delta G = delta G0 + 2.303 RT log Q at any other concentrations than standard conditions.
= -51,432 + 2.303 x8.314 x 460 x log [(2.55)2/ (0.325)(o.101)]
= -31,565 J
= -31.565 kJ
