Vedclass · Answer

(A) For the reaction: $((CH_3)_2CHN)_2N_{2(g)} \rightarrow N_{2(g)} + C_6H_{14(g)}$Let the initial pressure of the reactant be $P_o$ at $t = 0$.At time $t$,let the pressure of the reactant decomposed be $x$.Initial: $P_o, 0, 0$At time $t$: $(P_o - x), x, x$The total pressure $P_t = (P_o - x) + x + x = P_o + x$.Therefore,$x = P_t - P_o$.The pressure of the reactant remaining at time $t$ is $P_{reactant} = P_o - x = P_o - (P_t - P_o) = 2P_o - P_t$.For a first-order reaction,the rate constant $K$ is given by:$K = \frac{2.303}{t} \log \frac{P_{initial}}{P_{remaining}}$$K = \frac{2.303}{t} \log \frac{P_o}{2P_o - P_t}$

What is the value of the rate constant of a first-order reaction if the slope of the graph between $\log_{10} \frac{[A]_0}{[A]_t}$ ($y$-axis) and time ($x$-axis) is $1 \times 10^{-3}$?

In a first-order reaction $A \rightarrow B,$ if $k$ is the rate constant and the initial concentration of the reactant $A$ is $0.5 \ M,$ then the half-life is:

If the rate constant for a first order reaction is $k$,the time $(t)$ required for the completion of $99\%$ of the reaction is given by:

The decomposition of $N_2O_5$ occurs as $2N_2O_5 \to 4NO_2 + O_2$ and follows first-order kinetics. Hence,

If the half-life of a first-order reaction is $6.93$ minutes, then the time required for the completion of $99\%$ of the reaction will be . . . . . . minutes. (Given: $\log 2 = 0.3010$)
