The given graph is a representation of kinetics of a reaction.
The y and x axes respectively are for zero and first order reactions, respectively are:
Option 1 -<p>Zero order ( y = concentration and x = time), first order ( y = t₁/₂ and x = concentration)<br><!-- [if !supportLineBreakNewLine]--><br><!--[endif]--></p>
Option 2 -<p>Zero order ( y = concentration and x = time), first order ( y = rate constant and x = concentration)<br><!-- [if !supportLineBreakNewLine]--><br><!--[endif]--></p>
Option 3 -<p>Zero order ( y = rate and x = concentration ), first order (y = t₁/₂ and x = concentration)<br><!-- [if !supportLineBreakNewLine]--><br><!--[endif]--></p>
Option 4 -<p>Zero order (y = rate and x = concentration ), first order (y = rate and y = t₁/₂)</p>
For a zero-order reaction Rate Vs conc graph will be straight line parallel to the x-axis. For a 1st order reaction t? /? vs concentration will again be a straight line parallel to x-axis.
