The statement correct for the processes are spontaneous reaction have negative Delta H and non-spontaneous reaction has positive Delta H. Hence, option A is correct.

The value of Delta H in the reaction is the change in enthalpy of the reaction. The enthalpy of the reaction determines the reaction to be spontaneous or non-spontaneous.

<h3>What determines spontaneous and non-spontaneous reaction?</h3>

The spontaneous reaction is required with the energy input for the reaction to proceed. The energy is required by the system thus, the value of Delta H is negative.

The non-spontaneous reaction requires with the loss of energy in the formation of the product. The energy released gives the values of Delta H positive.

Thus, the statement correct for the processes are spontaneous reaction have negative Delta H and non-spontaneous reaction has positive Delta H. Hence, option A is correct.

A sample of octane burns releasing 2290 J of heat to the surroundings, and the gases produced expands against a piston to do 560
dexar [7]

<u>Answer:</u> The internal energy change for the reaction is -2850 J

<u>Explanation:</u>

  • <u>Sign convention of heat:</u>

When heat is absorbed, the sign of heat is taken to be positive and when heat is released, the sign of heat is taken to be negative.

  • <u>Sign convention of work:</u>

Work done for expansion process is taken as negative and work done for compression is taken as positive.

According to the First law of thermodynamics,

\Delta U=q+w

where,

\Delta U = internal energy

q = heat absorbed or released  = -2290 J

w = work done = -560 J

Putting values in above equation, we get:

\Delta U=(-2290)+(-560)\\\\\Delta U=-2850J

Hence, the internal energy change for the reaction is -2850 J
