Q: What is the difference between reaction rate and equilibrium constant (K_c)?

Reaction rate describes how fast reactants are converted into products (kinetics). The equilibrium constant K_c describes the relative ratio of products to reactants when forward and reverse rates are balanced at equilibrium (thermodynamics). A catalyst increases the rate but does not change K_c.

Q: How does temperature affect chemical equilibrium?

According to Le Chatelier's principle, increasing temperature favors the endothermic direction (which absorbs excess heat), increasing its K_c. For an exothermic reaction (heat producing), increasing temperature shifts the equilibrium toward reactants, decreasing K_c.

What is reaction kinetics & equilibrium?

Chemical reactions proceed according to collision theory: reactant molecules must collide with sufficient kinetic energy exceeding the activation energy barrier (E_a) and in the proper stereochemical orientation. The temperature dependence of the rate constant is modeled by the Arrhenius equation (k = A e^(-E_a/RT)). In reversible systems, dynamic equilibrium is reached when forward and reverse reaction rates become equal, governed by the equilibrium constant K_c.
