Answer to Question #96074 in General Chemistry for Solpos

Question #96074
Solve and use the appropriate number of significant figures.

A solution is 0.100 M in substances A and B, which react by a first-order reaction. If the reaction is 15.0% complete in 6.75 min, what is its half-life under these conditions? What would be the half-life if A and B were each at 0.200 M, and how long would it take for 15.0% completion of the reaction?

According to statement reaction gors through first order kinetics si from the given data we got from there the reaction constant 0.010 min -1

So half life under these condition 66.27 min if the order of the recation remain same half life will be same as first order reaction doesn't depend on reactant concentration
