Question

Derive integrated rate equation for zero order reaction​

Answer 1

Answer:

The above equation is known as integrated rate equation for zero order reactions. We can observe the above equation as an equation of straight line with concentration of reactant on y-axis and time on x-axis. ... The negative of the slope of this straight line gives us the value of rate constant, k.

An equation representing the dependence of the rate of reaction on the concentration of reacting species is known as differential rate equation. Instantaneous rate of reaction is expressed as the slope of the tangent at any instant of time in the concentration- time graph. Hence, it is very difficult to determine the rate of reaction from the concentration-time graph. Therefore, we integrate the differential rate equation to obtain a relation between the concentration at different points and rate constant. This equation is known as integrated rate equation. For reactions of different order, we observe different integrated rate equations.

Zero order reaction: In zero order reaction, the rate of reaction depends upon the zeroth power of concentration of reactants. Zero order reactions are very rarely observed. Some examples of zero order reactions are: thermal decomposition of HI on gold surface, decomposition of gaseous ammonia on a hot platinum surface etc. A general equation for a zero order reaction with rate constant k is derived below:
