Question 1 The diagram below can be used to express the energetics of both the forward and reverse reactions for A + B \(\rightleftharpoons\) C + D. What do the energies labeled by X and Y represent? Potential Energy X Y Reaction progress OX = Reaction enthalpy, Y = Activation energy for the reverse reaction OX = Activation energy for the forward reaction, Y = Reaction enthalpy OX = Activation energy for the reverse reaction, Y = Reaction enthalpy OX = Reaction enthalpy, Y = Activation energy for the forward reaction

00:01 Student we have an question that is just here we see this graph or diagram so here the progression of the reaction then here in this side the potential energy which is in the form of kilojou which is given so here we give the answer of the question which is here asked so first question is act we write the potential energy of the reaction of the forward reaction is about dash kilojoule here we write so we know what we know the ab are the what the reagent you regard a b it is the first part of the question so you regard it is the first part which is a and b are what reactant you're registered a and b are reactant so its potential energy you record the potential energy is here what the ab are the reactant so here the reactant the potential energy starter form fruity therefore it is easy it's what it's potential energy is 40 kilojouly it is our answer for first part of the question now we come from the second part of the question here we write its energy so here we know c and d are the what are the products so its energy is here right over the energy is here the c and d are what the product so this line is belongs toward the 20 there therefore here the energy is became here 20 kilojoules so 20 kilojoules is our answer for second part of the question now we come from the third part of the question here we write its energy so here the activated complex is you write the activated complex is what the top part the top part then you write its energy it's energy is what the activated complex that is in the word the top part that means the top part is our word the hundred therefore here its energy is what hundred you write it 100 kilojoules so hundred kilojou is our answer for third part of the question now we come from the next part of the question here we calculate what the activated energy of the forward reaction so you're rated activated energy offered here i've written activated energy of forward he's right forward reaction so which is equal to its formula is here write word energy of activated complex energy offered activated complex minus energy he's right at energy of the reactant so here the energy of activated complex so which is your hundred kilojoule and the energy of the reactant which is here we have the 40 kilojoules so it is the product so here the reactant is what 40 kilojole so here you're putting this value so which is you rated 100 kilojoule minus 40 kilo jule so which is equal to here you get 60 kilojoule so now here the activated energy for the forward reaction which became 60 kilojoule now we come from the the next part of the question which is the five part so here we calculate the value of a del h so del h is equal to the formula of it formula of it what energy the record it formula is energy of product energy of product minus energy of what…
