3 hermogravimetric analysis For solid state reaction, rate constant (k) is calculated by kinetic eqn. d dt kf ( ) Ae R f ( ) (1) where, A ( pre-exponential factor) and (activation energy) are the Arrhenius parameters; α is the fractional reaction; t is time; R is the gas constant; is temperature in Kelvin, and f (α) is the kinetic function. In isothermal kinetic studies, the rate constant is given by: ) kt () where, d f ( ) g ( ) can be calculated by the integration of f(α). Under non-isothermal conditions, in which a sample is heated at a constant rate β=d/dt, the explicit temporal in equation (3) is eliminated through the trivial transformation, so that = +β, where is the starting temperature and is the temperature at any time t. Upon integration, eq. (1) may be written as: / R e A ) dt (3) O Doyle s equation leads by Integration of equation (3) by considering that reaction rate is negligible at low temperatures ) x u A e e A du P( x) R x u R O (4) where, u=/r and x is the corresponding value of u at which a fraction of material has been decomposed. he above equation can be reformulated as:

4 A ln ) ln P( x) B (5) R where, B is a constant for a particular reaction at a constant heating rate. he integral function P(x) has no analytical solution; it may be written in an expanded form and estimated by using a procedure of trial-and-error type involving iteration.

So, it is assumed that the term (1 R/) is approximately constant and equal to unity. herefore, plotting the left hand side of the above equations against 1/ gives the slope -.33/R which yields the value of activation energy and the intercept gives value of A with excellent correlation coefficients, which indicates a good fit of the linear function.
