Transition state is a highly unstable, intermediate geometry between reactants and products, corresponding to the highest potential energy, requires the activation energy or Gibbs free energy for its its formation. The detailed solution is given below:
Which of the following statements correctly describe the transition state of a reaction? Select all that...
Which of the following statements correctly describe the half-life of a reaction? Select all that apply. Check all that apply. The half-life of a first-order reaction is independent of the initial concentration. The half-life of a reaction is related to its rate constant. The half-life of a reaction is the time taken for (A)to drop to half its original value. A chemical reaction is complete after two half-lives have passed. The half-life of a reaction is always a constant value.
All apply to the Hammond postulate except: The structure of a transition state resembles the structure of the nearest unstable species Transition states for exergonic steps structurally resemble reactants Transition states for endergonic steps structurally resemble reaction products All correctly apply to the Hammond postulate
Which of the following statements correctly describe a chemical change? Select all that apply! Only the physical form of the substance is changed during a chemical change. A chemical change involves a change in phase without a change in composition. The physical properties of the substance are changed during a chemical change. The composition of the substance is altered during a chemical change.
Which of the following statements correctly describe melting and melting point? Select all that apply. Check all that apply. The temperature of a solid rises steadily during the melting process. At the melting point of a substance the solid and liquid phases are in equilibrium Pressure changes have little effect on the melting point of a substance. During melting the kinetic energy of the particles increases dramatically
Select all the statements that correctly describe the formation of sp hybrid orbitals. Check all that apply. The formation of sp hybrid orbitals leaves one unhybridized p orbital. An sp hybrid orbital is identical to an sp hybrid orbital in shape and energy. Three sp² hybrid orbitals are formed by the hybridization of one s and one p orbital. A group of sp hybrid orbitals assumes a trigonal planar geometry, Do you know the answer I know it Think so...
