The rate constant for this first‑order reaction is0.870 s−1 at 400 ∘C. A⟶products How long, in seconds, would it take for the co

Marrrta [24]

Answer:

Time required is 1.33 seconds

Explanation:

For first order reaction, the rate law expression is:

$kt = ln \frac{[A_{0}]}{[A_{t}]}$

Where

A0 = initial concentration = 0.830 M

At = concentration after time t = 0.260 M

t = time in seconds = ?

k = rate constant = 0.870 s⁻¹

time = $[\frac{1}{k}](ln[\frac{0.830}{0.260}])$

time = $\frac{1}{0.870}(1.16) = 1.33 seconds$

If a balloon has a volume of 1.696 L at a pressure of 2.11 0 atmospheres, what will be the volume of the balloon if the pressure

Mazyrski [523]

Answer:

I think that the volume will be 1.414

Explanation:

According to the formula of boyle's law P1 V1 = P2 V2

We have to find V2 so:

V2 = P2/P1 V1

By putting the values:

V2 = 5.06/2.11 * 1.696

V2 = 5.06/3.578

V2 = 1.414
