Question

Question

Answer 1

Answer #1

Option 1:

Delta H is negative.

So, heat is released and the reaction is exothermic.

Option 2:

Since beaker is getting warmer, the reaction must have released the heat.

So, this is exothermic reaction.

Option 3:

Here heat is added on reactant side.

So, heat is being absorbed.

So, this is endothermic reaction.

Option 4:

Here heat is added on product side.

So, heat is being released.

So, this is exothermic reaction.

Answer: option 3

Answer 2
