I can read it on two different computers?

Based on their activation energies and energy changes and assuming that all collision factors are the same, which of the following reactions would be fastest in the reverse direction?

Based on their activation energies and energy changes and assuming that all collision factors are the same, which of the following reactions would be fastest in the reverse direction?

Which will be slowest?

Which will be slowest?

Ea= Ea3 = 55 kJ/mol , E= E3 = 7 kJ/mol . Ea= Ea1 = 43 kJ/mol , E= E1 = -24 kJ/mol . Ea= Ea2 = 38 kJ/mol , E= E2 = -10 kJ/mol . Ea= 38 kJ/mol , E= E2 = -10 kJ/mol and Ea= 55 kJ/mol , E= E3 = 7 kJ/mol . stry.com/lnyct/ltemvlew:assignmentProblemID=92520 140 Based on their activation energies and energy changes and assuming that all collision factors are the same which of the folowing reactions would be fastest in the reverse direction?

Explanation / Answer

The activation energy is the energy required to be overcomed by the reactants before the reaction can occour..In other words its an energy barrier which reactants has to corssed so lower the activation energy fast will be the reaction and higher the activation energy slower will be the reaction,

(a) Ea= Ea3 = 55 kJ/mol , E= E3 = 7 kJ/mol endthermic reaction

(b) Ea= Ea1 = 43 kJ/mol , E= E1 = -24 kJ/mol . exothermic reaction

(c) Ea= Ea2 = 38 kJ/mol , E= E2 = -10 kJ/mol exothermic reaction

slowest reaction (a) as it has highest activation energy and endothermic reaction  

fastest in reverse direction : (a) as in reverse direction this reaction will be exothermic
