Answer #1

1)
here half life is independent of concentration.
So, it must be 1st order reaction
Answer: 1

2)
Rate = k [A]^x

Since rate becomes 9 times when A becomes 3 times and 3^2 is 9, value of x is 2
Answer: 2

3)
Rate = k [A]^x

Since rate becomes 1.73 times when A becomes 3 times and 3^1/2 is 1.73, value of x is 1/2
Answer: 0.5

4)
Half life is not changing here.
Half life is constant for 1st order reaction
Answer: 1

5)
Rate of decrease of concentration is constant for 0 order reaction.
[A] = [A]o – k*t
So, order is 0
Answer: 0

    The half-life of a reaction, t1/2, is the time it takes for the reactant concentration [A] to decrease by half. For example, after one half-life the concentration falls from the initial concentration [A]0 to [A]0/2, after a second half-life to [A]0/4, after a third half-life to [A]0/8, and so on. on. For a first-order reaction, the half-life is constant. It depends only on the rate constant k and not on the reactant concentration. It is expressed as t1/2=0.693k For a...

    The integrated rate law allows chemists to predict the reactant concentration after a certain amount of time, or the time it would take for a certain concentration to be reached. The integrated rate law for a first-order reaction is: [A]=[A]0e−kt Now say we are particularly interested in the time it would take for the concentration to become one-half of its initial value. Then we could substitute [A]02 for [A] and rearrange the equation to: t1/2=0.693k This equation calculates the time...
