Question

The E of a reaction in presence of a catalyst is 4.15 kJ/mol and in absence of a catalyst is 8.3 kJ/mol. What is the slope of plot of ln k vs in absence of catalyst.

(A) +1
(B) –1
(C) +1000
(D) –1000 a 1 T (1) +1 (2) –1 (3) +1000 (4) –1000 a 1 T During electrolysis of aqueous solution of CuSO using Pt-electrode, the pH of solution :- (1) Increases (2) Decreases (3) Remains unchanged (4) Cannot be predicted 4 4 The amount of heat liberated when one mole of NaOH reacts with one mole of CH COOH is :- (1) 13.7 kcal (2) More than 13.7 kcal (3) Less than 13.7 kcal (4) Cannot be predicted 3 (1) 13.7 kcal 3 The suitable indicator for the titration of weak acid and strong base should have a pH range between :- (1) 3-5 (2) 7-11 (3) 4-6 (4) 2-3 (1) 3-5 (2) 7-11 (3) 4-6 (4) 2-3 Assertion :- In a mixture of two liquids A & B if then y will always be greater than y where y = mole fraction of A in vapour phase & y = mole fraction of B in vapour phase. Reason :- Raoult's law is applicable only for miscible liquid. (1) Assertion & Reason both are correct. (2) Assertion is correct but Reason is incorrect. (3) Assertion is incorrect but Reason is correct. (4) Assertion & Reason both are incorrect. P o A > P o B A B A B P o A > P o B A B A B 1001OMD303029230152 PHASE - MOCK TEST-2
