00:01 In this question we need to identify the curve that currently represents the entropy of the system as during a process right so first of all we can say that entropy or s symbol basically represents the disorderiness right it represents the disorderliness of the system right so now we can say that during a process during a process we can say that during a process a disorderliness or the end entropy can increase it can increase or it can decrease right for example for example if we take the example of co plus if we take the example of basically calcium carbonate let's say right so calcium carbonate dissociates into calcium oxide and carbon dioxide gas right so here there was only one mole of a molecule while on the product side we get two moles of molecules right or two moles of products so we can say that since the number of moles of particle increases in the system the overall disorderliness increases and the entropy increases as well right the entropy increases as well now we can say that we are taking 2h2 plus o2 and what we get is two moles of water so initially there were three moles of particles while after the reaction happens or after the process completes only two moles of product would be there right so since the overall number of particle decreases the overall disorderliness or the overall entropy should also decrease so we can say that entropy can increase or decrease however out of the given options only one seems correct right because we are taking graph of entropy versus time right so then we can say that when the reaction happens or when the process happens either it can decrease or it can increase or it can increase the only thing is that it should never start from here.

02:01 Entropy would never be zero.

02:03 Even if time is zero, even if the process has not started, the reactants or the starting materials should always have some kind of entropy value...
