Entropy increase A) with every reaction B) only in open systems C) only under certain reaction conditions D) only in the physical world. This cannot happen in cells otherwise cells would lose their needed energy

Identify the letter (A, B, C) that indicates the change in the energy of the entire reaction according to this energy profile. Explain why you choose the particular energy change. Include in your answer information about the ones you did not chose. alyzed Reaction Energy Exothermic Reaction Profile

what is free Gibbs energy and write the expression of free energy change. Define the exergonic and endergonic processes.

if the reaction given below occurs and pure A and B were mixed, which of the following would take place as equilibrium was established A + B ⇌ C a. the concentration of C would increase for a time, then remain constant b. the concentration of A would increase for a time, then decrease c. the concentration of B would increase for a time, then remain constant

What energy requirements must be met in order for a reaction to be favorable?

Label the following statements true or false: (a) A reaction is said to be spontaneous when it can proceed in either the forward or reverse direction. (b) A spontaneous process always happens very quickly.

The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches that can be made from a set number of ingredients. Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 36 slices of bread and 51 slices of cheese.

In the lab, a group of students is carrying out the reaction described and graphed in the previous question, but it is not proceeding. One student suggests heating it up to make it proceed more rapidly. Another student suggests adding an enzyme to the reaction instead. They try both and find that heating speeds up the reaction, and adding an enzyme also speeds up the reaction. A) How does heating the reaction in a test tube cause the reaction to occur at a higher rate? B) How does adding an enzyme enable the reaction to occur at a faster rate?

What is expected to happen to the reaction rate with increasing temperature? (Enzyme kinetics)
