WebIn applied mathematicsand the calculus of variations, the first variationof a functionalJ(y) is defined as the linear functional δJ(y){\displaystyle \delta J(y)}mapping the function hto WebThe solid-liquid-gas phase transition of most substances is first order. When the free energy exhibits continuous first derivatives but discontinuous second derivatives, the phase transition is called second order. Examples of this type of phase transition are the order-disorder transition in paramagnetic materials.

In applied mathematics and the calculus of variations, the first variation of a functional J(y) is defined as the linear functional mapping the function h to where y and h are functions, and ε is a scalar. This is recognizable as the Gateaux derivative of the functional. In a Riemannian manifold M with metric tensor g, the length L of a continuously differentiable curve γ : [a,b] → M is defined by The distance d(p, q) between two points p and q of M is defined as the infimum of the length taken over all continuous, piecewise continuously differentiable curves γ : [a,b] → M such that γ(a) = p and γ(b) = q. In Riemannian geometry, all geodesics are locally distance-minimizing paths, but t… WebIn order to calculate the activation energy we need an equation that relates the rate constant of a reaction with the temperature (energy) of the system. This equation is called the Arrhenius Equation: Where Z (or A in modern times) is a constant related to the geometry needed, k is the rate constant, R is the gas constant (8.314 J/mol-K), T is ... redacting signatures
