In this problem, it is asked that which statement is true of an endothermic reaction? right.
00:13
And the options are given a, strong bonds break and weak bonds form, right? and weak bonds break and strong bond form.
00:24
The bonds that break and those that form are of approximately same strength.
00:36
So our answer is option a, that is strong bonds break and weak bonds formed.
01:09
How? let us see.
01:10
So we know explanation is what? we know a few things about exothermic reaction and endothermic reaction.
01:19
So what is that? so let us say this is reactant.
01:24
Any reactant suppose and this is product right so for deluge to be negative deluge means enthalpy that is negative right negative means what this is exotherle right so for this the bond energy bond energy bond energy is high for the product right and for reactant bond energy is low.
02:16
But similarly, if we talk about exothermic reaction, this is first one and this is second one is bond energy of reactant here is more than bond energy of product in exothermic reaction...
