Dive into the world of equations along with Environmental Chemistry Important Questions for JEE Main and amplify your study sessions. Explore our Chemistry formula pages to start your preparation journey for JEE Main today!


Important Equations of Environmental Chemistry

1. Beer-Lambert Law:

$A = \varepsilon \cdot c \cdot l$

Where A is the absorbance, $\varepsilon$ is the molar absorptivity, c is the concentration, and l is the path length.


2. Rate of Reaction:   

$\text{Rate} = \frac{\Delta \text{Concentration}}{\Delta \text{Time}}$


3. Henry's Law:

$\text{Solubility of gas} = k_H \cdot P$

Where $k_{H}$ is Henry's law constant, P is the partial pressure of the gas.


4. Gibbs-Helmholtz Equation:

$\Delta G = \Delta H - T \cdot \Delta S$

Where $\Delta G$ is the Gibbs free energy change, $\Delta H$ is the enthalpy change, $\Delta S$ is the entropy change, and T is the temperature.


5. Nernst Equation:

$E = E^\circ - \frac{0.0591}{n} \cdot \log(Q)$

Where E is the cell potential, $E^{\circ}$ is the standard cell potential, n is the number of moles of electrons exchanged, and Q is the reaction quotient.


6. First Order Reaction Rate Equation:

$\text{Rate} = k \cdot [A]$

Where k is the rate constant and [A] is the concentration of the reactant.


7. Langmuir Adsorption Isotherm:

$\frac{x}{m} = \frac{K \cdot P}{1 + K \cdot P}$

Where x is the mass of the gas adsorbed, m is the mass of the adsorbent, P is the pressure of the gas, and K is the adsorption equilibrium constant.
