Ecological Pyramid vs. Reaction Thermodynamics Utilizzo e statistiche
Ecological Pyramid K12 app helps children to understand the ecosystem of the earth. For better understanding of children, the food chain is explained using animation. This app also includes the explanation for Food Chain process and their hierarchy and the pyramid of numbers.
==Features==
Theory - Explains in detail about Ecological Pyramid and its Food chain process.
Procedure - Get to travel through the Ecosystem.
Food chain - This K12 app explains children visually about the food chain which starts with the primary producers like plants, trees and then proceed through primary consumers - herbivores , further to omnivores, then continues till carnivores using animation.
Ecological pyramid - Provides an interactive level for children to assess their level of understanding about Food chain Hierarchy.
Download the Ecological Pyramid app and other K12 education apps published by Ajax Media Tech and make your children shine in science. Unlike a static or video based education model, which is non-interactive, K12 simulator apps are fully interactive and developed based on adaptive learning.

Reaction Thermodynamics helps in evaluation of main thermodynamic parameters of a chemical reaction.
Application calculates the following parameters:
- Standard free Gibbs energy, enthalpy and entropy from formation energy parameters.
- Reaction quotient (Q) from concentrations, pressures and reaction stoichiometry.
- Non standard energy parameters (dG, dH, dS) from standard ones, quotient and temperature.
- Reaction equilibrium constant, Keq.
- Van't Hoff relation to follow change in equilibrium constant with temperature assuming constant reaction enthalpy.
List of Formulas:
Quotient = Π(C, P)
ΔGº = Σ(ΔGºf)
ΔHº = Σ(ΔHºf)
ΔSº = Σ(Sºf)
ΔG = ΔH – TΔS
ΔGº = - RTlnKeq
Keq = e^(-ΔGº/RT)
ΔG = ΔGº + RTlnQ
ΔGº = ΔHº – TΔSº
ΔHº = ΔGº + TΔSº
ΔSº = (ΔHº - ΔGº)/T
Keq2 = Keq⋅e^(ΔHº/R⋅(1/T1 - 1/T2))"
Scrolling to the required formula and pressing run button initiates calculation according to the formula and set results in the appropriate fields ((dG°, dH°, dS°, Keq, dG, dH, dS, Keq2) and in the fields for standard parameters. Please pay attention to the parameters needed for solution of the formulas.
If formation parameters are unknown, the standard parameters can be filled in directly.
The default units are kJ/mole for dG and dH, kJ/Kmole for dS. Keq units depend on reaction stoichiometry and may be unitless or any mixture of Molar and atm.
Important!!! If compound doesn't participate in equilibrium calculation (like in case of water in water solution or solid in gas phase reaction) please set concentration of the compound to 1 or set its stoichiometric coefficient to 0 (depends on case) to ensure proper Quotient calculations. Ask developer directly in case of a ambiguity.
Reaction stoichiometric parameters and concentration/pressure units can be changed by pressing the corresponding fields.
