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