How can be activation energy for a reaction be determined graphically?
(a) Plot k versus \( T \), the slope of the line will be equal to \( E_{a} \)
(b) Plot \( 1 /[\mathrm{A}]_{t} \) versus \( t \), the slope of the line will be equal to \( E_{\mathrm{a}} \)
(c) Plot \( \ln [\mathrm{A}]_{\mathrm{t}} \) versus , the slope of the line will be equal to \( -E_{\mathrm{a}} \)
(d) Plot \( \ln k \) versus \( 1 / T \), the slope of the line will be equal to \( -E_{a} / R \)
