When A + B --> C then this reaction occurs in water, heat is given off.
1) Will the temperature of water go up or go down ?
- is the asnwer down ? since the energy is released to the surrounding.
2) What is the sign for delta H ?
+ or - ?
if the reaction gives off heat, the water must absorb it: temp goes up.
Exothermic reactions deltaH is negative.
Thanks for the help.
So in endothermic reaction deltaH is positive ?
