Question
When the reaction is an exothermic process,
Choose all that apply.
Enthalpy of the products is less than the enthalpy of the reactants
Work is done on the system
The q of the surroundings is a negative quantity.
The heat released by the reaction = The heat of absorbed by the surroundings
The temperature of the surroundings drops.
Enthalpy of the products is less than the enthalpy of the reactants
Work is done on the system
The q of the surroundings is a negative quantity.
The heat released by the reaction = The heat of absorbed by the surroundings
The temperature of the surroundings drops.
Explanation / Answer
In exothermic reaction:
1.Enthalpy of product is less than enthalpy of the reactants.
2.work is done by the system
3.When q is negative heat has flowed from the system results in positive q surrounding.
4.The heat released by the system is equal to heat absorbed by surrounding from fist law of thermodynamics.
5.The temperature of the surrounding rise.
So answer is a and d only.
