$\Delta S_{surr}$ for an exothermic reaction is

Which of the following is a state function?

Assertion : Water in liquid state is more stable than ice at room temperature.
Reason : Water in liquid form has higher entropy than ice.

Which of the following equations indicates an increase in entropy?

State the characteristics of entropy.

Calculate the increase in entropy (approximate) of $3 \ mol$ of hydrogen gas as it changes from $300 \ K$ at $0.1 \ atm$ to $1000 \ K$ and $1 \ atm$ $(C_p = 7 \ cal/degree/mol)$. $[log \ 3 = 0.48, \ ln \ x = 2.3 \ log \ x]$ .......$cal/degree$
