SINDH MDCAT 2016 PAPER SINDH MDCAT 2016 ( PART 7 ) 1. The term +dx/dt in the rate expression refers to the: Note: This question was cancelled Instantaneous rate of the reaction Increase in concentration of the reactant x Decrease in concentration of the reactant x Increase in solubility of the reactants 2. In which of the following reactions Kp > Kc ? 2SO2+ O2 ⇔ 2SO3 Both PCl5 ⇔ PCl3+Cl2 and N2+O2 ⇔ 2NO N2+O2 ⇔ 2NO PCl5 ⇔ PCl3+Cl2 N2+3H2 ⇔ 2NH3 3. Meta directing group is: -COR -NHR -OH -OR 4. A sample of ideal gas has a volume of 128 ml at -27 C to what temperature must the gas be heated at constant pressure if final volume is to be 214 ml? 140 C 120 C 138 C 150 C 130 C 5. 6,7-dimethyl-9-D-Pribitylosoalloxazine is the IUPAC name of: Tocopherol Nicotinic acid Riboflavin Thiamine Antirachitic 6. Fuming sulphuric acid contains: SO3 SO2 S3O3 S2O3 SO4 7. The principle quantum number is related to the: Spin of orbital Orientation of the orbital Orbital angular momentum Size of the orbital 8. Geometrical isomerism in alkenes is due to: Optical rotation about C = C bond Free rotation about C = C bond Restricted rotation about C = C bond Oscillation of H-tom between two polyvalent atoms 9. Trend of ionization energy in a group from top to bottom is: Remain same Constant Increases Increases then decreases Decreases 10.
