Question

Please answer I'll give you a MEDAL and FAN!!! just answer right
The rate law for a hypothetical reaction is rate = k [A][B]. If the concentrations of A and B are both 0.020 moles per liter and k = 1.3 × 10-1 M-1s-1, what is the reaction rate?

4.0 × 103 M

1.3 × 10-1 M-1s-1

5.2 × 10-5 Ms-1

5.2 × 105 Ms-1

Answer 1

Answer 2

please help me

Answer 3

they give you the concentrations for A and B (0.02M each)

plug in 0.02 for A and 0.02 for B, and 1.3 × 10-1 for k, then solve the equation

Answer 4

ok so i got 5.2 x 10^-5

Answer 5

So, C

Answer 6

right
