Concentration of the limiting reactant (with initial concentration of a moles/litre) after time t is (a-x). Then ‘t’ for a first order reaction is given by________?
Ak. t = ln a/(a – x)
Bk. t = ln a (a – x)/x
Ck. t = x/a (a – x)
Dk. t = ln (a – x)/a
Correct answer
A. k. t = ln a/(a – x)
Explanation
The correct answer is k. t = ln a/(a – x).
