Hi, in the first part of the question we are given with the reaction in which a plus b converts into c plus t.
00:07
We are having the activation energy is equal to 102 kilojoule per mole.
00:13
The delta h0 reaction is equal to 49 kilojoule per mole.
00:17
We are asked to calculate activation energy of the reverse reaction in terms of kilojoule per mole.
00:24
The positive value of delta h0 reaction suggests that the reaction is endothermic.
00:33
Therefore we can draw the energy profile diagram for this given reaction.
00:46
In this way here we can see that the reactant energy is less than than product energy.
00:56
The reactant is a plus b and the product is c plus d.
01:01
Now we need to calculate ea dash that is activation energy of reverse reaction we can find out this as ea dash is equal to ea minus delta h0 reaction value we can substitute here as ea is given 102 kilojou per mole minus delta h0 reaction is given as 40 59 kilojoule per mole.
01:36
On subtraction we get the activation energy of reverse reaction is equal to 53 kilojoule per mole...
