(B) For a zero-order reaction,the rate law is given by $[R] = [R]_0 - kt$.At half-life $(t = t_{1/2})$,$[R] = [R]_0 / 2$.Substituting these values: $[R]_0 / 2 = [R]_0 - kt_{1/2}$.Rearranging gives $kt_{1/2} = [R]_0 / 2$,or $t_{1/2} = [R]_0 / (2k)$.From this expression,$t_{1/2} \propto [R]_0$ is $True$ $(T)$.Also,$t_{1/2} \propto 1/k$,so $t_{1/2} \propto k$ is $False$ $(F)$.Therefore,the correct sequence is $1-T, 2-F$.
