Explanation / Answer

1)

NH3 would increase the solubility and HN03 Has no effect virtually .

2)

the balanced reaction is given by

3 Cl2 + 6 OH- = ClO3- + 5 Cl- + 3 H2O

SO the coefficient of OH- is 6   

3) first reaction dn = change in number of gas moles = -1

second reaction dn= 0

third reaction dn = 1

fourth reaction dn= 0   

fifith reaction dn= 7

as dn = 7 is highest .

dS is most positive for the reaction

2NH4N03 ---> 2N2 + 02 + 4H20
