General Chemistry 2 Final Exam Questions and Answers | Latest Version | 2024/2025 | Graded A+ What determines the direction in which a chemical equilibrium will shift when the concentration of one of the reactants is increased? The equilibrium will shift to the right, towards the formation of more products, to counteract the increase in reactant concentration. How can you assess the strength of an acid or base using pH and pOH values? The strength of an acid or base can be asse...

AL 1.1 - what is the difference between actual change in free energy (delta G) and standard change in free energy (delta G knot) with regard to the spontaneity of the cell. correct answers Delta G knot can be used to predict the spontaneity of a reaction under standard conditions, which are 1 atm, 298K and all reactants and products are initially set at [1M]. Under these conditions, the reaction will be spontaneous if delta G knot <0 as defined by. Delta G knot = -RT lnKeq. Under cellular c...

MCAT General Chemistry (Princeton Review) Questions and Answers | Latest Update | 2024/2025 | Already Passed What is the role of a Lewis acid and a Lewis base in a chemical reaction? A Lewis acid is an electron pair acceptor, while a Lewis base is an electron pair donor. They interact to form a coordinate covalent bond where the base donates an electron pair to the acid. How does the concept of bond enthalpy relate to the strength of a chemical bond? Bond enthalpy (or bond dissoci...
