Areaction has a rate constant of 0.00774 sec-1, how much of the compound (in mol/l) is left after 8.93 sec, if there was 0.652 mol/l at the start? (give answer to 3 decimal places)?
how do you know the order of the

0.608 mol/L compound is left after 8.93 sec

Explanation:

This is a first order reaction because unit of rate constant is (or )

For a first order reaction, integrated rate law is-

where is initial concentration of reactant, is concentration of reactant after t time and k is rate constant

Here = 0.652 mol/L, k = 0.00774 ) and t = 8.93 sec

So,

So,

-be a crystalline solid

- be soluble in water

-conduct electricity

hope this : )
