This helped me in answering my modules for the second time already😅😊 Thank you very much for creating this video!

awesome video and very clear key pts of the chp :))

Thanks sir i think i understand the topic much better now

Thank you for the video, but how do we know the surrounding(>>0) outweighs the system which is negative, leading to a positive total entropy for this equation Cao(s)+CO2 - CaCo3.

Hi brother, I get the entropy thing. But if you see the equation at 6:53, the entropy is positive. But what if you had to compare it to another reaction that was positive and had all gaseous products. How do you determine which has a higher entropy?

Do we need to memorise the formula at 2:16?

[eshitaalexander]

where does -6010 come from? isn't the value -6.01 kJ mol (-1)

[xinyansheng]

wait...how do you know that Cao(s)+CO2 - CaCo3 is exothermic reaction?

[taiseisuzuki]

Where does the number of entropy of the system and enthalpy of the system?

[anonmela]

7:40 How do we know that the second reaction is exothermic?
