The Engineering, Agriculture and Medical Common Entrance Test (EAMCET) is being conducted by Jawaharlal Nehru Technological University Kakinada (JNTUK) on behalf of Andhra Pradesh State Council of Higher Education (APSCHE). This Examination is for admission into various professional courses offered in the University/Private Colleges in the State of Andhra Pradesh. Below are a few important chapters and concepts you need to consider while studying for this exam:
Rate of a chemical reaction; Factors influencing rate of a reaction: dependance of rate on concentration- rate expression and rate constant- order of a reaction, molecularity of a reaction; Integrated rate equations-zero order reactions-first order reactions- half life of a reaction; Pseudo first order reaction; Temperature dependence of the rate of a reaction -effect of catalyst; Collision theory of chemical reaction rates.
