For the reaction A(g)+2B(g)rarr2C(g)+3D(g),the value of DeltaE at 27^( – InterviewSolution

1.	For the reaction A(g)+2B(g)rarr2C(g)+3D(g),the value of DeltaE at 27^(@)C is 19.0 kcal. The value of DeltaH for the reaction would be (R=2.0 cal K^(-1) mol^(-1))
Answer» 20.8 KCAL 19.8 kcal 18.8 kcal 20.2 kcal Solution :USE `DeltaH=DeltaE+DeltanRT` `DeltaH=19+2xx2xx10^(-3)xx300=20.2 kcal , Deltan=2`.
