6) When a spontaneou s, endothermic reaction occurs at constant temperature and pressure, the entropy change of the surroundings is: a) impossible to tell b) positive c) negative d) zero a) ΔG > 0 One finds that the equilibrium constant for a particular reaction increases with increasing temperature. Assuming that the standard reaction enthalpy and entropy are temperature independent, this means that: a) The standard reaction enthalpy is less than zero 8) b) The standard reaction entropy is greater than...

Please answer the following question below
8. Consider 1 mole of a monatomic ideal gas undergoing the changes of state indicated on the Pressure-Temperature diagram below. 4 3 0 100 200 300 400 Temperature, K a. Calculate AU, q, w, and AH for the step AB b. Calculate AU, q, w, and AH for the step BC C. Can you prove a general and very simple expression for ΔΗ for an isothermal change of state of an ideal gas?

Part B Check all the correct statements. Note: Push yourself to understand why these statements are true or false. If false think about an example that contradicts the statement, or think about how you would formulate the statement so it is correct. You will n you can answer a similar question that is formulated differently The internal energy of any gas (ie. not necessarily ideal) depends only the temperature of the system The kinetic energy of any gas (i.e. not...

For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour. System Change AS O AS < 0 AS = 0 O AS...

6. The formula dS = dQ/T makes it look like a system can only increase its entropy by absorbing heat. You must however remember that this equation is only true for reversible processes. Entropy can change for a system without absorbing any heat. Consider the following scenario. You are given an insulated container with two compartments. The whole container is at the temperature T which remains constant. One compartment has a volume V1 and has n1 moles of an ideal...

Indicate whether the following experimental mistake will increase, decrease, or have no effect on the calculated value of R. A student completed the experiment without waiting for the test tube to cool after heating. Select ALL of the correct answers. a. All measurements should be made at the same temperature. b. The volume measured from the beaker will be high. c. The measured temperature is room temperature. d. The calculated value of Ris low. e. The calculated value of Ris...

If a potato core is allowed to dehydrate by sitting in open air, would the water potential of the potato cells decrease or increase
If a potato core is allowed to dehydrate by sitting in open air, would the water potential of the potato cells decrease or increase? i think it decreases but i'm not sure. and if a plant cell has a lower water potential than its surroundings and if pressure=0, is the cell hypertonic(in terms of solute concentration) or hypotonic to its environment? will the cell gain or lose water? any ideas...?http://en.wikipedia.org/wiki/Water_potentialanalysis queswhat is water potential?Osmosis Lab /27819 Name: ________________________________ Date: ___________...
