Question

When a given reaction is conducted in a calorimeter, energy is absorbed from the surrounding water that results in a decrease in the water’s temperature. Which of the following potential energy diagrams best illustrates the energy change of this dissolving process?

I really need some help.

Answer 3

since when did i become a person to call in chemistry problems o.O lol

Answer 4

@Callisto or @mukushla Do you think you could help me with this question?

Answer 5

sorry...i cant..

Answer 6

It's okay mukashla.

Hmm, if you increase the temperature, the kinetic energy of molecules in the calorimeter should be increased, and potential energy is stayed constant.Particles move faster, <c^2> increased. Internal energy increased.

But if you're talking about the water, as lattice structure is 'formed'/bonds formation/forces between molecules increased. So, no change in kinetic energy, potential energy decreases, internal energy decreases for water.

Thanks .Sam.
