Question

Express the relation between the half-life period of a reactant and its initial concentration if the reaction involved is of zero order​

Answer 1

The half-life is the time required for a quantity to fall to half its initial value, as measured at the beginning of the time period. If we know the integrated rate laws, we can determine the half-lives for first-, second-, and zero-order reactions. For this discussion, we will focus on reactions with a single reactant. For nth order, half life can be given as: t subscript 1 divided by 2 space end subscript equals space fraction numerator 2 to the power of n minus 1 end exponent space minus space 1 over denominator left parenthesis n minus 1 right parenthesis k space left square bracket A right square bracket subscript 0 to the power of n minus 1 end exponent end fraction
