derivative of a constant

Initial Rate Method - This method is used for reactions where more than one reactant species are involved. Initial rates of the reaction are determined by varying the concentration of only one reactant while keeping the concentrations of other reactants constant. Initial rate of reaction ..

Now, from thermodynamics, it is known that the equilibrium constant K is related to the free energy of the reaction. Hence, D G for the formation of the transition state is, which the free energy of activation is given by, Then the equation for k transforms to The same derivation..

Radiocarbon The 1 4 C so produced is eventually converted into CO 2 , which in turn is incorporated into plants and trees by the process of photosynthesis and then finds way into animals, which eat plants. As there is a natural plant-animal cycle, an equilibrium is set up and all living matter cont..

The expression for acceleration due to gravity ..

The velocity-time graph for uniformly accelerated rectilinear motion (motion along a straight line), a > 0, is illustrated in the figure. The velocity-time graph for a uniformly retarded motion is as shown in the figure. Here a < 0, indicating retardation or deceleration. In this sectio..

Similarly LPG, which contains butane and biogas,CNG which contains methane combust releasing energy as follows: Carbohydrates are the major consituent of our food. The carbohydrates are broken to glucose or its derivatives in our body. The glucose burns to give energy to our body. The hea..

-D-glucose. When either of the two forms is dissolved in water and allowed to stand, the specific rotation of the solution changes slowly and reaches a constant value at +52.5 o . This equilibrium is reached faster if a trace of acid or base catalyst is present. The spontaneous change in..

Acceleration due to Gravity on Moon - The expression for acceleration due to gravity is Where G is the universal gravitation constant, M is the mass of the heavenly body which produces acceleration in a body and R is the radius of the heavenly body. The equation for g shows that the value..

This relationship may be derived in the following manner: (1) For a salt of the type AB Let the solubility of sparingly soluble salt AB at a certain temperature be 'S' moles per litre. Then..

We have learnt that of D G is a measure of the spontaneity of a chemical reaction. It can be shown that the free energy of a process is equal to maximum possible work that can be derived from the process as given below: From first law of thermodynamics, it is known that D E = q + w, where..
