ETEA PAST PAPER 2020 ( PART 8 ) 1. Which of the following reaction has greater Kp than Kc (kp>Kc) NO2 + 3H2 ↔ 2NH3 2SO2 + O2 ↔ 2SO3 2NOCL ↔ 2NO + Cl2 2NO + Cl2 ↔ 2NOCl 2. The equation N2g + 3H2g = 2NH3, represents: Solvay process Avogadro’s law Haber’s process Contact process 3. The unit of the rate constant is the same as that of the rate of reaction in: First order reaction Second order reaction Zero order reaction Third order reaction 4. The study of rates of chemical reactions and the factors that affect the rates of chemical reactions is known as: Chemical kinetics Electrochemistry Thermodynamics Stoichiometry 5. For the reaction A(g) → products, when the concentration of A(g) doubles, the rate of reaction increases four fold, which means it is: Zero order reaction First order reaction Second order reaction Negative order reaction 6. For which of the following order of the reaction, rate of reaction in inversely proportional to the concentration reaction? 2nd order reaction Zero order of reaction Negative order of reaction 1st order reaction 7. The thermal energy at constant pressure is called: Internal energy Enthalpy Work done Heat capacity 8. Born-Haber cycle is used to determine the lattice energies of: Metallic solids Molecular solids Covalent solids Ionic solids 9. One calorie is equal to: 0.418 KJ 4.18 KJ 4.18 0.418 KJ mol 10. The oxidation state of ‘S’ in the (S2O3)^-2 is: -2 +6 +2 +4 Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
