Question

N2(g) + 3H2(g) --> 2NH3(g)+ 22,000. ^H =
a) 22,000 kcal
b)-22,000 kcal
c)22 kcal
b)-22 kcal

Answer 1

Can't answer. You didn't include the units for the 22,000. 22,000 what? The rules are that if it is exothermic, and this reaction is because it tells you it reacts and gives off heat, then delta H is negative. So delta H = -22,000 somethings or -22 somethings. The answer is either b or d(typo--the second b must be d).
