Calculation OF the entropy change OF the surroundings : As = grev T General Equation Ag surr = 9 SUIT IT 9 surr = -9 syst (First law OF Thermody namics) AS surr = -9 - SYS/T At Constant Pressure ; asyst = ACH Assum = 1 Arti°/T Example calculate the entr OPY change OF the surroundings for the following reaction : 2 Nacs) + C'2 (9) 2 Na a (s) ArH = - Q22 ks/mol Always as some at 25 °C iF not told temp ! Even Though the reaction is highly exc, the Surroundings are So vast ,they are ass amed to be at the Some temp A S surr = - -ArH2 = - 1-Q22KJ/md ) x 1000 J T 248.15K las surroundings = 2.75 x recieved lots OF heat From system
