In probability theory, the conditional probability of an event A given that another event B has occurred is defined as the probability of A given B, written as P(A|B). It is a function of the probability of B, the probability of A given B, and the probability of B.

In chemistry, kinetics is the study of the rates of chemical reactions. The rate of a reaction is the change in concentration of a reactant over time. The rate of reaction is dependent on the concentration of the reactants, temperature, and the activation energy of the reaction.

the solution off. The answer is dead. The term half life off a reaction is time required for the reactant concentration to drop toe half its original value. For our first order reaction, the half life is expressed as follows For first order reaction, it will be t half equal to 0.693 Divide by cave hair K is the real constant anti office, the half life off The reaction from the expression off the half life given about it is clear that half life over first order reaction is independent off the react and concentration it is given that 75% off sample decomposes in 60 minute. So after 60 minute 25% which is equal to one by fourth off, original compound is left to decompose. It means to lives are involved toe get compound from yeah, initial toe one by four, off amount. So to multiply by t half equal to 60 minutes, Antifa from here will be called to 30 minutes. No. So therefore the half life period off the compound is 30 minute. Yeah. So this is the little explanation step by step. Please go through this. Thank you.
