For the reaction, a → b, the rate constant is 0.0208 m-1 sec-1. How long would it take for [a] to decrease from 0.100 to 0.0450
goldfiish [28.3K]

First, assume the order of the given reaction is n, then the rate of reaction i.e. \frac{dx}{dt}=k\times[A]^{n}

where, dx is change in concentration of A in small time interval dt and k is rate constant.

According to units of rate constant, the reaction is of second order.

\frac{1}{[A]_{t}}-\frac{1}{[A]_{o}} = kt   (second order formula)

Put the values,

\frac{1}{0.04590 m}-\frac{1}{0.100 m} =0.0208 m^{-1}s^{-1} \times t  

 22.23 m -10 m =0.0208 m^{-1}s^{-1} \times t

\frac{12.23 m}{0.0208 m^{-1}s^{-1}} = t

t= 587.9 s

Hence, time taken is 587.9 s

What temperature of air can hold the most water
S_A_V [24]

At -40 °C (-40 °F), however, it can hold no more than 0.2 percent. When a volume of air at a given temperature holds the maximum amount of water vapour, the air is said to be saturated. Relative humidity is the water-vapour content of the air relative to its content at saturation.
