The rate constant for this first‑order reaction is 0.740 s − 1 0.740 s−1 at 400 ∘ C. 400 ∘C. A ⟶ products A⟶products How long, i
sesenic [268]

Answer:

1.668 S

Step-by-step explanation:

We are given that

A\rightarrowProduct

For first order reaction,

t=\frac{1}{k}ln\frac{A_0}{A}

t=\frac{2.303}{k}log\frac{A_0}{A}

Rate constant=k=0.740s^{-1}

Temperature=T=400^{\circ}

We have to find the time taken by the reaction when concentration of A to decrease from 0.790 M to 0.230 M.

A_0=0.79 M

A=0.230

Substitute the values then we get

t=\frac{2.303}{0.740}log\frac{0.79}{0.23}

t=1.668 s

Hence, it would take 1.668 s for the concentration of  A to decrease from 0.790 M to 0.230 M.
