The magnitude of work done (in kcal) when 120 gm of Mg (s) is reacted – InterviewSolution

1.	The magnitude of work done (in kcal) when 120 gm of Mg (s) is reacted with excess of hydrochloric acid in an open vessel at 27^@C is
Answer» Solution :MAGNITUDE of W=3 kcal `Mg(s)+2HCL(AQ)toMgCl_2(s)+H_2(G)uarr` `W= -P_(ed)(V_2-V_1)= -Deltan_(g)RT= - 5XX(2xx300)/1000=-3` kcal
