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 controlled conditions in the..

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 particl..

Kinetic Stability of Fuels - At normal temperature, fuels are stable even in the presence of air. This is because, the activation energy of combustion reaction is high. When a mixture of fuel and air is burned, a flame has to be applied, that is the mixture has to be ignited. Near the fla..

. Transition State explains the rate of reaction in term of formation of a transition state of reacting molecules. The formation of transition state requires energy of activation. Transition state theory connects kinetic rates with thermodynamic properties of reactants and the transition ..

At normal temperature, fuels are stable even in the presence of air. This is because, the activation energy of combustion reaction is high. When a mixture of fuel and air is burned, a flame has to be applied, that is the mixture has to be ignited. Near the flame, the contents are raised to high tem..

When a gas is heated the molecules move faster increasing the pressure. But to maintain the pressure constant, the force of collision is compensated with an increase in volume. So, at constant pressure the volume of the gas increases with temperature. By kinetic gas equation we have, ..

Kinetic energy is given as R = 8.314 JK - 1 mol - 1 , T= 273 - 23 = 250 K 9. Calculate the root mean square speed of methane molecules at 2..
