I need help answering all of these with WORK BEING SHOWN PLEASE

From a consideration of the phase diagram below, a change from point L to point k corresponds to: sublimation condensation freezing evaporation boiling All the following can function as bronsted base EXCEPT: NH_3 NaF KNO_3 CH_3 CH_2 NH KHC_2 O_4 Which of the following solutions would be expected to have the highest boiling point? 0.010 m HF 0.010 m H_2 SO_3 0.010 m Na_2 SO_4 0010 m HNO_3 For which of the following values of the equilibrium constant does the equilibrium consists mainly of reactants (ie reactants are favored in the equilibrium) ? 10^5 10^3 10^0 10^-3 10^-5 For which of the following equilibria would K_c=K_p? Carbon tetrachloride reacts with oxygen at high temperature to produce chlorine and carbonyl chloride. 2 CCl_4 (g) + O_2 (g) 2 COCl_2(g) + 2 Cl_2 (g) K_c = 1.9 times 10^19 What is K_c for the following reaction? COCI_2 (g) + Cl_2 (g) CCl_4 (g) + 1/2 O_2 (g) 5.3 times 10^-20 2.3 times 10^-10 4.4 times 10^9 -1.9 times 10^19 1.9 times 10^10 For the reaction system: 2 HI (g) H_2(g) + I_2 (g) K_c = 0.020 at 447 degree C. If the concentration of H_1, H_2, and I_2 are all 1.50 times 10^-3 M at 447 degree C, which one of the following statements is CORRECT? The system is at equilibrium The concentration of I_2 and H_2 will increase to obtain equilibrium. The concentration of HI and I_2 will increase to obtain equilibrium. The concentration of HI will increase to obtain equilibrium. The concentration of HI and H_2 will decrease to obtain equilibrium.

Explanation / Answer

(17) The species whcih accepts proton is called Bronsted base and the species which loses a proton is called Bronsted acid.

(c) KNO3 It is salt of strong acid and strong base which undergoes complete ionisation. It does not hydrolyse.

(18) The solution which has more number of solute particles can have more value for colligative property.

(c) Na2SO4 (aq) ----------> 2 Na+ (aq.) + SO42- (aq.) 3 paticles are formed from each unit

(19) (d) 10-5 smaller the K value larger the ability of equilibrium position to exist towards reactants side.

(20) (b) because same number of gaseous reactants and gaseous products.
