Question
Topic/s: Thermochemistry, Properties of Gases, Intermolecular Forces, and Properties of Solutions.
Show the effect of each of the following by making the proper arrow head(s) in the equation.
1.) SbCl5 == SbCl3 + Cl2 remove SbCl3.
2.) 2ICl == I2 + Cl2 add I2
3.) CO + Cl2 == COCl2 add Cl2
4.) CaO(s) + SO3 == CaSO4(s) decrease Pressure
5.) PCl3 + Cl2 == PCl5 increase Pressure
6.) N2 + 3H2 == 2NH3 deltaH= -22.1 kcal increase Temperature
7.) H2 + I2 == 2HI + 2.26 kcal decrease Temperature
8.) 2NOCl == 2NO + Cl2 deltaH=75kJ increase Temperature
Explanation / Answer
Solved the first four parts as per Chegg guidelines, post multiple question to get the remaining answers
1) SbCl5 ==== SbCl3 + Cl2
The SbCl3 will present in the solid state, hence there will be no affect on the removal of SbCl3.
2) 2ICl ====> I2 + Cl2
K = [I2][Cl2]/[ICl]^2, the addition of I2 will reduce concentration of products, hence the reaction will shift in the forward direction
3) CO + Cl2 ========> COCl2
Addition of reactants will shift the reaction in the right hand side to neutralize the reduction in Kc value
4) CaO(s) + SO3 <======== CaSO4(s)
Kp = 1/[P(SO3)], decrease in the pressure will increase Kp, hence the reaction will shift in the left direction
