Zero order: $(y =$ concentration $, x =$ time $), \quad$ First order: $(y = t_{1/2}, x =$ concentration $)$

Zero order: $(y =$ concentration $, x =$ time $), \quad$ First order: $(y =$ rate constant $, x =$

Zero order: $(y =$ rate $, x =$ concentration $), \quad$ First order: $(y = t_{1/2}, x =$

Zero order: $(y =$ rate $, x =$ concentration $), \quad$ First order: $(y =$ rate $, x = t_{1/2})$

Explanation

To solve this problem, we need to understand the graphical representation of zero-order and first-order reactions. $\newline$ The graph provided shows a constant line, which is characteristic of a zero-order reaction. $\newline$ For zero-order reactions: $\newline •$ The rate of reaction is independent of the concentration of the reactant. $\newline •$ The concentration of the reactant decreases linearly with time. $\newline •$ Thus, a plot of concentration vs. time is a straight line. $\newline$
