What is the cell potential called when all reactants and products are in their standard states at 298.15 K? equilibrium potential cell potential (Ecell) reference potential standard cell potential (E∘cell)

standard cell potential (E∘cell)

What is the half-cell called that is based on hydrogen ion production and assigned a potential of exactly 0 V under standard conditions? calomel electrode standard hydrogen electrode (SHE) reference electrode silver/silver chloride electrode

standard hydrogen electrode (SHE)

For chemicals to react, what must occur between their molecules? They must collide with one another so that their electrons can be either transferred or rearranged. They must dissolve in a solvent. They must be exposed to light. They must be heated to a high temperature.

They must collide with one another so that their electrons can be either transferred or rearranged.

Why does a higher temperature result in a higher reaction rate? Molecules gain more electrons. Molecules become larger and more reactive. Molecules change their chemical structure. Molecules move faster and can collide more.

Molecules move faster and can collide more.

What effect does decreasing the concentration of reactants have on a chemical reaction? A reaction will remain unchanged. A reaction will slow down due to the decreased number of collisions. A reaction will stop completely. A reaction will speed up due to increased energy.

A reaction will slow down due to the decreased number of collisions.

How does increasing the surface area of reactants affect a chemical reaction? It reduces the energy required for the reaction. It changes the chemical composition of the reactants. It gives the particles more opportunity to come into contact with one another. It decreases the reaction rate.

It gives the particles more opportunity to come into contact with one another.

What is a process called that occurs without any outside intervention? Spontaneous (thermodynamically favored) process Exothermic process Non-spontaneous process Endothermic process

Spontaneous (thermodynamically favored) process
