Titanium is purified by reaction with iodine and subsequent high temperature treatment The process is commonly known as:

Fusion reaction takes place at high temperature because

Phenol on reaction with H_2SO_4 at high temperature gives mainly

The phenomenon of induction of flowering upon low temperature treatment is known as?

Assertion : If both DeltaH^(@) and DeltaS^(@) are positive then reaction will be spontaneous at high temperature. Reason : All processes with positive entropy change are spontaneous.

Assertion: Vernalization is acceleration of subsequent flowering by low temperature treatment. Reason: Site of vernalization is apical meristem.

Low temperature treatment to speed up the process of flowering is referred to as

Low temperature treatment to speed up the process of flowering is referred to as

Name the following The process of heating an ore to a high temperature in the presence of air.

Name the following: The process of heating an ore to a high temperature in the presence of air.

Gibbs Helmholtz equation relates the enthalpy, entropy and free energy change of the process at constant pressure and temperature as DeltaG=DeltaH-TDeltaS " (at constant P, T)" In General the magnitude of DeltaH does not change much with the change in temperature but the terms TDeltaS changes appreciably. Hence in some process spontaneity is very much dependent on temperature and such processes are generally known as entropy driven process. When CaCO_(3) is heated to a high temperature it decomposes into CaO and CO_(2) , however it is quite stable at room temperature. It can be explained by the fact that
