Explanation Given: The following incomplete table, ∆H ∆S ∆G Low Temperature High Temperature - + - Spontaneous ---------------------- - - Temperature dependent ------------------ ---------------------- + + ---------------------- --------------------- Spontaneous ---------------------- - -------------------- Nonspontaneous Nonspontaneous Formula used: The free energy change can be defined as follows, ∆ G = ∆ H − T ∆ S Where ∆ G is the free energy change at constant pressure and temperature, ∆ H is the enthalpy change, T is the temperature and ∆ S is the entropy change. Calculation: Using the previous formula complete the table If ∆H is negative and ∆S is positive, ∆G will be negative independently of the temperature. If ∆H and ∆S are negative, ∆G depends of temperature. If the temperature is low, the ∆ H term is higher than the T ∆ S term in the equation...

Thermochemistry

Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that …

Exergonic Reaction

The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energ…

Part A Identify each alcohol as primary, secondary, or tertiary Drag the appropriate items to their respective bins. CH₂ H₂C- -C-OH HO CH₂ Primary Он OH CH₂ OH CCH₂OH CH₂ сн Secondary Tertiary Reset Help CH,CH₂ (CH)CHCH,OH CH,CH,CH,CCH, CHOH CH₂ Different types of alcohol groups Alcohol and its reaction: 8. Combing two alcohol molecules below and completing the reaction with Product .( Hint Reaction called etherification as ether is formed and name the ether once you complete the reaction. Hint.: R-O-H+H-O-RR-O-R Do the reaction: CH₂OH + CH₂OH---→ + H-O-H 9. Write the reaction of formation of alcohol from alkene by adding water: Addition reaction also called hydration reaction as we are adding water which occur always in presence of acid Hint: Break the double bond and add H and OH if symmetrical then add anywhere if unsymmetrical then follow Markovnikov rule H should go to that double bone carbon which has more hydrogen CH2=CH2 + H₂O-→
