Previous1234567891011121314151617Next 5. Which one of the following is an essential nutrient of plants? Potassium Sodium Lead Aluminum 6. In a kinetic experiment, a student placed crystals of iodine in a closed reaction vessel, introduced a given quantity of hydrogen gas, and collected data to calculate the rate of formation of hydrogen iodide. What would be the effect obtained on the rate of the reaction, if the student takes more amount of iodine from that used in the first experiment? The rate of the reaction will be constant. The formation of hydrogen iodide will be decreased. It lowers the rate of the reaction. It speeds up the rate of the reaction. 7. Which of the following CORRECTLY relates the vapor pressure of a liquid with its boiling point? Boiling point is the temperature at which the kinetic energy of molecules is much less than the intermolecular force. the temperature at which molecules present in the vapor phase go back to the liquid state. the temperature at which the vapor pressure becomes equal to the external pressure. the temperature at which all the three physical state co-exist. 8. Consider this equilibrium system:CO(g)+FeO4(s)⇌COO2(g)+3FeO(s)Which of the following disturbances shift the equilibrium position to the right? Adding Fe3O4 (s) Removing FeO (s) Removing CO (g) Removing CO₂ (g) 9. Which one of the following resulted from interaction of the atomic orbitals of bonding atoms to produce new electron distribution associated with the entire molecule? Bohr orbit Electron orbit Molecular orbital Hybrid orbital Previous1234567891011121314151617Next We have provided these questions from previous years grade 12 Ethiopian Secondary School Leaving Certificate Examination (ESSLCE) exams with the sole purpose of assisting students in their studies and preparations for upcoming exams.
