[ n = \frac0.2540.00 = 0.00625 \ \textmol, \quad C = \frac0.006250.250 = 0.0250 \ \textM ] 3.2 Chemical Kinetics Rate law example: [ \textRate = k[A]^m[B]^n ]

Equilibrium: [N₂] = 0.1 – (x), [H₂] = 0.3 – 3(x), [NH₃] = 2(x). Then (K_c = \frac(2x)^2(0.1-x)(0.3-3x)^3). Solve for (x) (approximation if (K_c) small). 3.4 Thermodynamics Gibbs free energy: [ \Delta G = \Delta H - T\Delta S ] Introduction to Contextual Maths in Chemistry .pdf

A sample gives (A = 0.45) in a 1 cm cuvette, (\varepsilon = 9000 \ \textM^-1\textcm^-1). Find (c). [ n = \frac0

Given concentration–time data, determine (k) and order using integrated rate laws (linear plots: ([A]) vs (t) for zero order, (\ln[A]) vs (t) for first order, (1/[A]) vs (t) for second order). 3.3 Equilibrium & ICE Tables Example: For ( \textN_2 + 3\textH_2 \rightleftharpoons 2\textNH_3 ), initial [N₂] = 0.1 M, [H₂] = 0.3 M, 0 initial NH₃. Let (x) = change in [N₂]. initial [N₂] = 0.1 M
