What can be concluded regarding a spontaneous reaction that becomes nonspontaneous when the temperature is increased? O The reaction is exothermic and represents an increase in entropy. O The reaction is endothermic and represents a decrease in entropy. O The reaction is endothermic and represents an increase in entropy. O The reaction takes place in the gas phase. O The reaction is exothermic and represents a decrease in entropy.

is this question true or false

Life is sometimes described as a constant struggle against the second law of thermodynamics. How do organisms succeed in this struggle?

chemical reations that release energy are called_______________reaction?

In discussing the energy of a physiological system, the Gibbs free energy is most relevant. Since the value of entropy cannot be known, change in the Gibbs free energy is more commonly used. In order to get reliable result we should hold all variables constant except the one we are interested in measuring. If you are interested in studying respiration in this perspective, which one of the following should be measured? Select one: a. Change in temperature b. Change in length c. Change in number of molecules d. Change in electrical charge e. Change in pressure

Which answers apply. (There could be more than one)  Hydrolysis of ATP into ADP and inorganic phosphate releases energy because the reaction... a.) oxidizes ATP b.) reduces ATP c.) increases resonance d.) decreases resonance e.) increases entropy f.) decreases entropy

a) Often, we want to think about entropy as the sum of the entropy of an organism and itssurroundings. Write a version of the second law including these two entropies. b. How does this help you understand how an organism can become more ordered andstill obey the 2nd law? c. Name some spontaneous processes that increase the entropy of the surroundings whileincreasing the order in an organism.

what happens in a chemical reaction?  what does activation energy (EA) mean?

Select the best answer or answers from the choices given: Factors that accelerate the rate of chemical reactions include all but (a) the presence of catalysts, (b) increasing the temperature, (c) increasing the particle size, (d) increasing the concentration of the reactants.

If Hydrogen Peroxide (H2O2) is added to each of the following items, which of the items will have exergonics reactions? Items with endergonic reactions? - chicken - raw potato slice - raw carrot slice - sour cream
