Randomness and Spontaneity
Randomness and Spontaneity - In order to find out some other factor that may be responsible for the feasibility of a process, let us examine endothermic reactions. The simplest process occurring without any energy change (where D H is almost zero) may be illustrated wi..

>When neither the metal atom (M), nor the metal ion Mn+ undergo any change no charge is developed on the electrode relative to the solution. If the metal has relatively high tendency to get oxidized, its atoms will lose electrons readily and form Mn + ions, which go into the solution. The electrons..

. When the rate of adsorption equals the rate of desorption, dynamic equilibrium is attained. If q is the fraction of the total available surface covered with gas molecules, at any instant, then (1- q ) is the fraction of the surface of the solid which is empty. From kinetic theory of gas..

Chemical Kinetics
Introduction - Processes by which substances are transformed to one or several products are called chemical reactions. Chemical processes that occur in the presence of light, like sunlight, are called photochemical reactions. These processes can occur naturally or under controll..
Order of a Reaction
Order of a Reaction - The order of reaction is determined with respect to each reactant in the reaction. The order of a reaction is the power to which the concentration of a reactant is raised. This is the order with re..

Cyclopropane (C 3 H 6 ) at room temperature has a ring structure. When it is heated, the ring opens up and cyclopropane isomerizes to propylen..
Fractional Order Reaction or Complex Order
Hydrogen (H 2 ) gas reacts with bromine (Br 2 ) gas to give hydrogen bromide vapo..
Kinetic Molecular Theory of Gases
Kinetic Molecular Theory of Gases - In order to explain the observed behaviour of gases, a model was proposed based on the molecular and kinetic concept of gas molecules. This model takes into account the particulate nature of matter and the constant movement of partic..

This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
I think the tutors knew their stuff really well and was very helpful. math was actually something I dread.not anymore ,Thank you Tutor Vista - jennifer,New york
