Enthalpy of formation Study guides, Class notes & Summaries

MCAT General Chemistry | Latest Update | 2024/2025 | Already Passed What is the role of the conjugate base in an acid-base reaction, and how does it influence the reaction equilibrium? The conjugate base is formed when an acid donates a proton. It influences the reaction equilibrium by interacting with the acid, shifting the equilibrium based on the relative strengths of the acid and its conjugate base. How does the presence of a common ion affect the solubility of a salt in a solu...

rate of reaction ֎ -:- the change in concentration of a reactant or product per unit time rate constant (k) ֎ -:- The constant that links the rate of reaction with the concentrations of the reactants raised to the powers of their orders in the rate equation. half-life ֎ -:- The time taken for the concentration of the reactant to reduce by half Benzene ֎ -:- a naturally occurring aromatic compound, which is a very stable planar ring structure with delocalised electrons Model ֎ -...
