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 condit..

. 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 ..

01. Calculate the kinetic energy of a body of mass 5 kg, which is moving with a velocity of 15m/s. Solution: Mass of the body (m) = 5kg Velocity of the body (v) = 15m/s Kinetic energy = 1/2mv 2 Kinetic energy = 562.5 J 02. A dog of mass 20kg is running at a con..

>Matter consists of molecules. These are the smallest particles, which are capable of free existence and retain all the chemical properties of the parent substance. The molecules are always in a state of random continuous motion. The molecules exert forces on one another. These forces dep..

Internal Energy - Every substance possesses a definite quantity of energy, under a given set of factors such as chemical nature of the substance, temperature and pressure. The total energy contained in a system or substance is called its internal energy or intrinsic energy. It is represen..

Heating Effects: Joule's Law - When a potential difference is applied across the ends of a conductor, the free electrons are accelerated and acquire kinetic energy. As the electrons move through, they collide with the positive ions and atoms of the conductor and transfer their kineti..

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 correspond..

We come across in our day-to-day life different forms of energy, like the mechanical energy, heat energy, electrical energy, chemical energy etc. Here in this chapter, we are mainly concerned with mechanical energy. The two types of mechanical energy are kinetic energy and poten..
