Assertion:The SI unit of entropy is JK^(-1)mol^(-1) Reason: DeltaS=(q_(rev))/(T)

DeltaS=(q_(rev))/(T) , so

DeltaS=(q_(rev))/(T) , so

The units of DeltaS are JK^(-1) mol^(-1) .

Explain change in entropy of a system during a reversible process Delta S = (q_(rev))/(T)

As per second law of thermodynamics a process taken place spontaneously if and only if the entropy of the universe increases due to the process. Change in entropy is given by Delta S = (Q_(rev))/(T) What is the change in entropy of the universe due to the following reaction occuring at 27^(@)C ? A + 2B rarr C + 2D, Delta H = +1.8 kJ mol^(-1) Molar entropy values of A, B, C and D are 1,2,3 and 4 JK^(-1) mol^(-1) respectively.

For the hypothetical reaction A_(2)(g) + B_(2)(g) hArr 2AB(g) If Delta_(r)G^(@) and Delta_(r)S^(@) are 20 JK^(-1)mol^(-1) respectively at 200 K. Delta_(r)C_(p) is 20 JK^(-1) mol^(-1) then Delta_(r)H^(@) "at" 400 K is :
