For a first-order reaction R \(\rightarrow\) P at a given temperature, \(k\) is the rate constant. For this reaction, at the given temperature, the concentrations of R and P at a time \(t\) are [R] and [P], respectively. The correct graphical representation(s) for this reaction is(are)

For a reversible reaction \( R \rightleftharpoons P \), at constant temperature, both the forward and the backward reactions are first order elementary reactions with rate constants \( k_f \) and \( k_b \), respectively. At time zero, the concentration of \( R \) is \( [R]_0 \) and the concentration of \( P \) is zero. At any given time, \( [R] \) and \( [P] \) are the concentrations of \( R \) and \( P \), respectively. If \( k_b = 4k_f \), the correct graphical representation of the reaction is:
