is 22.060 kcal .
is 22.060 kcal . B
The heat given out when one gram molecule of HCl is formed from its elements at 298 K is 22.060 kcal .
C
The heat absorbed when one atom of hydrogen reacts with one atom of chlorine to form one molecule of HCl at 
and one atom of chlorine to form one molecule of HCl at 
and one atmosphere pressure is 22.060 kcal .
and one atom of chlorine to form one molecule of HCl at and one atmosphere pressure is 22.060 kcal . D
The heat absorbed when one gram equivalent of HCl is formed from its elements at 298 K is 22.060 kcal .
Text Solution
Verified by ExpertsThe correct answer is:
B
Negative sign indicates that heat is given out. So this equation indicates that 22060 cal or 22.06 kcal heat is given out on formation of 1 mole of HCl
