Will fan and medal if you answer right
The rate law for a hypothetical reaction is rate = k [A]2. When the concentration is 0.10 moles/liter, the rate is 2.7 × 105 M*s1. What is the value of k?
2.7 × 103
2.7 × 103 M1s1
7.2 × 105 M1s1
2.7 × 104 M1s1

Best ResponseYou've already chosen the best response.1plug in 2.7 * 10^5 for rate, and 0.1 for A, then solve for k

Best ResponseYou've already chosen the best response.1uh, I'm not sure you can do that on a calculator 0.0027 = 2.7 * 10 ^ x find x

Best ResponseYou've already chosen the best response.1not quite, try again... how many places do you have to move the decimal point to get from 0.0027 to 2.7?

Best ResponseYou've already chosen the best response.1right! so, 0.0027 = 2.7 * 10^(3) now, the units of k are M1s1 so our answer becomes 2.7 * 10^(3) M1s1
