Calculate Delta S for 3 moles of a diatomic ideal gas which is heated and compressed from 298K and 1bar to 596K and 4 bar

Calculate Delta S for 3 moles of a diatomic ideal gas which is heated

1.	Calculate Delta S for 3 moles of a diatomic ideal gas which is heated and compressed from 298K and 1bar to 596K and 4 bar
Answer» `-14.7 "CAL" K^(-1)` `+14.7 "cal" K^(-1)` `-4.9 "cal" K^(-1)` `6.3 "cal" K^(-1)` Solution :`Delta S = nCP "LN" (T_(2))/(T_(1)) + nR "ln" (P_(1))/(P_(2))` `=3 xx (7)/(2) xx2 xx l n (596)/(298) + 3 xx 2 xx l n (1)/(4) = 6.3` cal/K
