When the initial concentration of crystal Violet is double, the rate of the reaction will rise up about four times the initial rate.

<h3>What is the rate of chemical reaction?</h3>

The rate of a chemical reaction refer to the rate of change in concentration of the reaction over the change in time. Introduction.

When you double the concentration the rate doubles. The rate is proportional to the square of the concentration of a reactant. When the rate is doubled the concentration rate goes up four times. The rate is not affected by the concentration of a reactant.

A sample of radioactive waste has a half-live of 40 years and an activity level of 4 curies. After how many years will the activ
Westkost [7]

After 160 years, the activity level of the sample will be 0.5 curies.

<h3>What is half-life?</h3>

Half life of any radioactive waste is the half decay of that product.

The formula is \dfrac{\lambda }{\lambda_1} = 2^\dfrac{a}{b}

Where, λ is 4 cruies

λ1 is 0.5 cruies

b = 40 years

Putting the values in the equation

\dfrac{4}{0.5} = 2^\dfrac{a}{40}\\\\\\\dfrac{a}{40} =  4\\ = 160 years

Thus, the correct option is 160 years.
