Two substances R and S decompose in solution independently, both following first order kinetics. The rate constant of R is twice that of S. Initially 0.5 millimoles of R and 0.25 of S. The molarities of R and S will be equal at the end of time equal to:
1
twice the half-life of R
2
twice the half-life of S
3
the half-life of S
4
the half-life of R
