Using standard absolute entropies at 298K, calculate the entropy change for the system when 1.62 moles of NH4NO3(aq) react at standard conditions.

Select all that apply. using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 (s) pb+2(aq) + 2cl -(aq). the concentration of the products yield a ksp of 2.1 x 10-2:
