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 - ?

  • Chemistry (11th) -

    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 ?

  • Chemistry (11th) -

    yes,positive.

    thnx
