0.0625g remains from 1g of a radioactive element after 20 years of radioactive decay. Determine the rate constant and half-life `(t_(1//2))` of the reaction. How much of the element did remain after 10 years from the start?

What is meant by pseudo unimolecular reaction? Explain with an example. 0.0625 g remains from 1 g of a radioactive element after 20 years of radioctive decay. Determine the rate constant and half-life (t_(1//2) of the reaction. How much of the element did remain after 10 years from the start?

What is meant by pseudo unimolecular reaction. Explain with an example. 0.0625g remains from 1g of a radioactive element after 20 years of radioactive decay. Determine the rate constant and half-line (t1/2) of the reaction. How much of the element did remain after 10 years from the start.

Starting from 10g of a radioactive element, 0.25 g was left after 5 years. Calculate The amount left after one year.

Starting from 10g of a radioactive element, 0.25 g was left after 5 years. Calculate Rate constant for the decay of the radioactive element.

A radioactive substance has a half-life of 1 year. The fraction of this material, that would remain after 5 years will be.

Starting with 10 g of a radioactive substance 0.1 gis left after 10 days. The rate constant for the decay is:

The half-life of a radioactive element is 1600 y. What part of the element will remain after 6400 y ?

Starting from 10g of a radioactive element, 0.25 g was left after 5 years. Calculate The time required for half of the element to decay.

Initial mass of a radioactive element is 1 g. If 0.25 g of the element remains intact after 6 min then determine the half-life of the element .
