How is BQ activity calculated

The SI unit for activity, one decay per second, is called becquerel (Bq), in honor of the radioactivity pioneer. This means that 1 Bq equals 1 decay/s. Activity R can also be expressed in other units such as decays per minute and decays per annum.

How do you calculate specific activity of radioactivity?

Activity-Specific Activity

  1. Units can also be used to determine the total amount of radioactive atoms released by accidental or controlled releases.
  2. Units for Activity.
  3. Decay Law.
  4. (Number nuclei) N=A.e.lt (Activity). m=

How do you calculate decay constant from activity?

Let’s say N is the size the radioactive atom population at a time t. dN is how much the population decreases over time dt. The equation dN/dt=-lN gives the rate of change. l is the decay constant.

What is the SI unit of decay constant?

How do you calculate half time?

One quick way to find out this is to calculate how many half lives we have in the given time period. 6 days/2 days=3 half lives 100/2=50 (1 half life) 50/2=25 (2 half lives) 25/2=12.5 (3 half lives) So 12.5g of the isotope would remain after 6 days.

What is true for the process of zero-order?

A zero-order reaction is a reaction that occurs without regard to the concentration of reactants. Rate=k for a zero-order reactant is the rate law. k is the constant rate.

Which of the following expressions correct for zero-order and first order respectively where A is initial concentration?

So option B is correct.

How long after its start will the reaction be 75% complete if it is first order?

32 min

What is the unit for reaction rate?

Reaction rate is usually expressed in terms of the reactant or product consumed per unit of time. These units are expressed as moles per liter per unit of time (M/s, M/min or M/h ).
