Hess's Law A principle stating that the total enthalpy change of a reaction is the same, regardless of the steps taken. Enthalpy A measure of the total energy of a thermodynamic system, often associated with heat changes in chemical reactions. Delta H Symbol representing the change in enthalpy during a chemical reaction. Equilibrium Constant (K) A value that expresses the ratio of products to reactants at equilibrium for a reversible reaction. Sulfur Dioxide A chemical compound with the formula SO2, often involved in reactions forming sulfur trioxide. Sulfur Trioxide A chemical compound with the formula SO3, formed from sulfur dioxide and oxygen. Exponential Relationship A type of relationship where a change in one quantity results in a proportional change in another quantity's exponent. Inverse A mathematical operation that reverses the effect of another operation, such as flipping a fraction. Reciprocal The inverse of a number; for a fraction, it is obtained by swapping the numerator and denominator. Square Root A value that, when multiplied by itself, gives the original number, often used in calculating changes in K. Coefficient A numerical or constant quantity placed before and multiplying the variable in a chemical equation. Balanced Chemical Equation An equation where the number of atoms for each element is equal on both sides of the reaction. Mole A unit of measurement for amount of substance, representing Avogadro's number of particles. Reaction Direction The orientation of a chemical reaction, indicating which substances are reactants and which are products. Oxygen Gas A diatomic molecule with the formula O2, essential for combustion and respiration processes.
