Which of the following curves represents a first order reaction.A. B. C. D. All of these |
Answer» Correct Answer - D A first order reaction exhibits an exponential decay of the reaction concentration `[R_(t)=R_(0)e^(Kt)]` and a linear decay of the logarithm of the reactant concentration `[logR_(1)=logR_(0)-(k)/(2.303).t]` Integrated rate law for a first order reaction is `K=(2.303)/tlog(([R]_(0))/([R]_(t)))` or `log({:(([R]_(0))/([R]_(t)),=,((K)/(2.303)),t),(overset(uarr,)(y),=,overset(uarr)(m),overset(uarr)(x)):})` |
