Question

1st attempt See Periodic Table See Hint A reversible reaction that occurs in a single step has AH-47.2 kJ/mol and E) - 63.2 kJ/mol. What is the activation energy of the reverse reaction? 649 W/mol

Answer 1

Criven, DH= -47.2kJ/mol. Ea = 63.2 Kol mol - activation energy for forward ron L Negative DH value os exothermic and will be more than indicates that the hence the stability that of reactants .. reaction is of product for a general - A reaction B Energy profile for the reaction will be achvenon energy for reverse rxnn Rrogress of xxn -

According to given values and looking at energy profile diagram . Ea E = DH - Ea - Eb = - 47.2 kJ/mol. - En = 63.2 kJ/mol + 47.2 kJ/mol. - E 110.4 kJ/ mall This is the activation energy for the reverse reaction
