Question
K-TYPE answer format: Mark a if A.B.C are correct: b if A, c: e if B. D; d ifD only:otherwise. A. B. C. D. Free energy is a measure of randomness of the system. There is no relationship between either the sign or the magnitude of enthalpy and the rate at which a reaction occurs According to the 2nd Law of Thermodynamics some reactions are spontaneous in both directions at the same temperature. One of the driving forces which causes chemical reactions to occur is the tendency for systems to become more random K-TYPE Answer Format: Marka if A.B.care correct; b ?A.c; c i/B. D: d if Donly: e otherwise. A. Cl2 and Cr20,2 are common oxidizing agents. B. O2 is a better oxidizing agent than MnO4 C. The oxidation number of P in Na3PO4 is +5. D. Fe is a better reducing agent than Al. Given the reactioh 3 Ag(s)+ Cr3+(a) 3 Agt(aq)+ Cr(s) choose the correct statements using K-TYPE Answer Format: Marka if A. B, C are correct: b if A, C B, D: d if D only: e otherwise. A. Ag(s) is oxidized as the reaction above proceeds. Ag(s) loses electrons as the reaction above proceeds. C. Cr3+(aq) is the oxidizing agent in the reaction above. D. If the reaction Z(s)+ p2t(a)-tag)+ Ps) proceeds spontaneously,then z2t (a) is a better oxidizing agent than P2+(a). the correct statements from the following using K-TYPE answer format: Mark a if A.B.C are correct: if A, C c if B, D: d if D only: e otherwise. A. NaCI is more soluble in pure water than in O.1 M KNO3 B. MnSO3 is probably not soluble in water. c. The solubility of Mg(NO3)2 decreases if acid is added to the solution. D. If it appears in an aqueous reaction alone, Ni would have to be as solid, i.e. could not be in solution.Explanation / Answer
1. Measure of randomness is entropy and second law doesn't state that some reactions are spontaneous in both direction .
So answer here is statement b & d are correct . That is (c)
2 . permanganate is very strong oxidizing agent and Fe isn't superior in comparison with Al here .
So statement A and C is correct . Option (b) .
