lechatelier's principle forward

If a system at equilibrium is subjected to a change in concentration, temperature or pressure, the equilibrium readjusts itself to counteract the effect of the applied chang..

Christian Huygen Huygen proposed a hypothesis for the geometrical construction of the position of a common wavefront at any instant during the propagations of waves in a medium. The postulates are: Every point on the given wavefront called 'primary wavefront' acts as a fresh source of new dis..

All moving objects in our daily life have well defined paths or trajectories. The path or trajectory of an object can be determined by knowing its position and velocity at various intervals of time. However, Werner Heisenberg, in 1927, pointed out that we can never measure accurately both the posit..

Changing the Position of Equilibrium - A reversible reaction attains equilibrium when the opposing reactions occur at an equal rate. Therefore, if a reaction at equilibrium is subjected to some change it changes the rate of one reaction more than the other. By changing the concentration, temperatur..

) by making more 'A' to react with B, to form more products. On the other hand, when the concentration of C (or any other product) is increased, the reaction will shift towards left (reactant side). Thus, according to Le Chatelier's principle in general, an increase in the concentration o..

According to the Le Chatelier's principle, this will make the reaction move in a direction which absorbs heat i.e., the endothermic process will be favoured. As vaporization (liquid g vapours) is an endothermic process, a rise in temperature will favour the process of vaporization i.e. m..

The value of Kw varies with the change in temperature. The values of [H 3 O + ] and [OH - ] are always equal to each other at all temperatures but the values of K w are different at different temperatures. The value of K w increases with the rise in temperature. This is because increase in te..
