R constant in arrhenius equation
Web1 day ago · A is a constant for a given reaction, called the pre-exponential factor (or A-factor). Often the equation is written in logarithmic form lnk=lnA – E a /RT A graph of lnk against 1/T is a straight line with a gradient –E a /R and an intercept on the lnk axis of lnA. It is named after Svante Arrhenius. k=Aexp(–E a /RT) lnk=lnA – E a /RT WebIn the Arrhenius equation, K = A e x p (− E a / R T). A may be termed as rate constant at infinite temperature. Whn, the temperature is infinite, the value of the term R T − E a becomes zero and the value of the term e x p (− R T E a ) becomes equal to 1. Hence, k = A
