Derive an expression for the rate constant of a first order reaction. Give its units.
Let us consider a first order reaction, A → product Suppose at the beginning of the reaction, that is, when t=0, the concentration of A is amolL and when t=t, the concentration of A is (a-x)molL. For a first order reaction, the rate of reaction, where k is the rate constant. integrating, Here, c is the … Read more
Find the value of half-life period.
Value of Half-Life Period From the law of radioactive disintegration, we know, If, be the half life period, then at, ,
Deduce the law of radioactive disintegration.
The Law of Radioactivity Disintegration: Let, N be the number of atoms present in the radio element at a given instant t. Then the rate of decrease, Here, λ is the disintegration constant. It is defined as the ratio of the amount of the substance which disintegrates in a unit time to the amount of … Read more
Derive the de Broglie wavelength for a charged particle of charge q and accelerated through a potential difference of V volts.
The Required de Broglie Wavelength: A photon of light of frequency has the momentum, But, . Therefore, the momentum of the photon can be expressed in terms of wavelength λ as, The wavelength of a photon is, therefore, specified by its momentum according to the relation, de Broglie suggested that the above equation is applicable for any … Read more
Derive the Einstein’s photoelectric equation.
Einstein’s Photoelectric Equation : According to Einstein, light of frequency consists of a shower of photons, is of energy . When a photon of light of frequency is incident on a metal, a part of the energy acquired by the electron is used to pull out the electron from the surface of the metal and the rest of … Read more
C++ Program (Source Code) for Priority Scheduling CPU Scheduling Algorithm
Priority Scheduling: In operating systems, tasks that are queued to be processed go through different scheduling algorithms in different operating systems. Priority Scheduling is one of them. Priority scheduling is like shortest job first except that the next job to process is selected not by the amount of time it will take, but by the … Read more
C++ Program (Source Code) for Round Robin (RR) CPU Scheduling Algorithm
Round Robin (RR): In operating systems, tasks that are queued to be processed go through different scheduling algorithms in different operating systems. Round Robing or RR is one of them. In round robin, like first come first served, the job or task that comes first, gets processed first, but not fully. Rather in round robin, … Read more
C++ Program (Source Code) for Preemptive Shortest Job First (SJF) CPU Scheduling Algorithm
Shortest Job First: In operating systems, tasks that are queued to be processed go through different scheduling algorithms in different operating systems. Shortest Job First or SJF is one of them. In shortest job first, literary, the smallest task among all the remaining tasks will get processed first. However, I explained Shortest Job First (SJF) … Read more
C++ Program (Source Code) for First Come First Served (FCFS) CPU Scheduling Algorithm
First Come First Served (FCFS): In operating systems, tasks that are queued to be processed go through different scheduling algorithms in different operating systems. First Come First Served or FCFS is one of them. In first come first served, literary, the task that comes first to be processed gets processed first, then the next one … Read more
