Chemical Kinetics Formulas JEE
Below is a table that covers all the important Chemical Kinetics Formulas JEE. Candidates can refer to the table given here for more streamlined accessibility:
|
Concept |
Formula |
Explanation |
|
Rate of Reaction |
|
Rate of change of concentration of reactants/products for reaction |
|
Rate Law |
|
Mathematical relation expressing rate as a function of reactant concentrations; m,nm,nm,n are reaction orders |
|
Order of Reaction |
|
Sum of powers of concentration terms in rate law |
|
Zero-Order Reaction |
|
Rate independent of concentration; half-life depends on initial concentration |
|
First-Order Reaction |
|
Rate proportional to concentration; half-life constant |
|
Nth-Order Reaction (n ≥ 2) |
|
General formula for reactions higher than first order |
|
Parallel Reaction |
|
For two competing reactions starting from same reactant |
|
Hydrolysis of Sucrose |
|
Used to study rate of sucrose hydrolysis; α = rotation |
|
Temperature Coefficient |
|
Factor by which rate increases on 10°C rise |
|
Arrhenius Equation |
|
Relates rate constant k with temperature; Ea = activation energy, A = frequency factor |
|
Collision Theory |
|
Reaction occurs when molecules collide with sufficient energy and proper orientation |
|
Radioactive Decay |
|
Decay of radioactive substances; λ = decay constant |
|
Integrated Rate for General Reaction |
|
Rate law integration gives concentration vs. time relation |
Chemical Kinetics Important Questions
Based on the Chemical Kinetics JEE Notes provided, here is the list of important questions. Check Chemical Kinetics Important Questions to prepare effectively:
| Chemical Kinetics Important Questions | |||
| S. No | Topic | Type of Question / Focus Area | Notes / Tips |
| 1 | Rate Laws | Determine rate expressions for reactions | Focus on order with respect to each reactant and overall order |
| 2 | Zero-Order Reactions | Time-dependent concentration changes | Use integrated form: ([A]_t = [A]0 - kt); calculate half-life (t{1/2} = [A]_0/2k) |
| 3 | First-Order Reactions | Exponential decay problems | Integrated form: ([A]_t = [A]0 e^{-kt}); half-life (t{1/2} = 0.693/k) |
| 4 | Nth-Order Reactions (n ≥ 2) | Concentration-time relationships | Use formula: (1/[A]_t^{n-1} - 1/[A]0^{n-1} = (n-1)kt); half-life (t{1/2} = 1/((n-1)k[A]_0^{n-1})) |
| 5 | Parallel Reactions | Multiple pathways | Total rate: (Rate = (k_1+k_2)[A]); ([A]_t = [A]_0 e^{-(k_1+k_2)t}) |
| 6 | Hydrolysis of Sucrose | Optical rotation-based kinetics | Use (k = (2.303/t) \log((r_\infty - r_0)/(r_\infty - r_t))); r = rotation due to S, G, F |
| 7 | Temperature Effects / Arrhenius Equation | Effect of temperature on rate constant | (k = A e^{-E_a/RT}); (\log(k_2/k_1) = (E_a/2.303R)(1/T_1 - 1/T_2)) |
| 8 | Radioactive Decay | Decay of nuclei over time | (N_t = N_0 e^{-\lambda t}); After n half-lives: (N = N_0/2^n); λ = decay constant |
