The following information is available for the reaction: $$R \rightarrow P$$
$$R \rightarrow P; rate = r_{1}$$
$$R \overset{A}\rightarrow P; rate = r_{2}$$
$$R \overset{B}\rightarrow P; rate = r_{3}$$
$$R \overset{C}\rightarrow P; rate = r_{4}$$
$$R \overset{D}\rightarrow P; rate = r_{5}$$
$$R \overset{A + C}\rightarrow P; rate = r_{6}$$
