Question

Wired Faculty App

When initial concentration of the reactant is doubled, the half-life period of a zero order reaction

Is halved

Is doubled

Remains unchanged

Is tripled

Solution

B.

Is doubled

${t_{(1 / 2)}}_{z e r o} = \frac{[A]_{0}}{2 k} ∴ I f [A]_{0} = d o u b l e d, t_{1 / 2} = d o u b l e d$

Some More Questions From Chemical Kinetics Chapter

The conversion of molecules X to Y follows second order kinetics. If concentration of X is increased to three times how will it affect the rate of formation of Y?

What will be the effect of temperature on rate constant?
