A reaction takes place in a balloon such that 425 J of heat are taken in from the surroundings and 193 J of work are done by the surroundings.

What is ΔE for the system? in J

What is ΔH for the surroundings? in J

What is ΔE for the universe? in J

Expert Solution

1) ΔE for for the system = Q - W

= 425 - 193

= 232 J

2) ΔH for the surroundings = - Q = -425 J

3)

surronding internal energy = work done by the system

ΔEsurroundings = 193 J

ΔE universe = ΔEsystem + ΔEsurroundings

= 232 + 193

= 425 J

For a given reaction, the heat capacity (CP) of the reactants is 50.0 J/mol K and for the products is 65.0 J/mol K. If the enthalpy of reaction is − 150.0 kJ/mol at 300K, what is the best estimate of ΔrxnH at 320K? The reaction in the previous question is carried out adiabatically starting at 300 K. What is the final temperature after the reaction goes to completion? ΔrxnH300 = -150.0 kJ/mol CP(reactants) = 50 J/molK CP(products) = 65 J/molK...

Experiment 2 – Light Independent Reaction After the light dependent reaction, the light independent takes place. During this phase, also known as the Calvin Cycle, the energy generated in the light independent phase is used to fixate the carbon atoms from carbon dioxide and glucose is produced. In this experiment you will use baby spinach leaves to demonstrate the utilization of carbon dioxide during the light independent reaction of photosynthesis. Phenol red is an organic dye that undergoes a color...
