The rate constant of substrate A for a reaction is 2 x 10-3 s-1. If the rate of reaction is 7 x 10-4 mol L-15-1 then the concentration of substrate A (in mol L-1) is

1.5 M
0.8 M
0.35 M
2.25 M

guys plz give me right ans.no spamiing plz
if u gave me right ans.i will mark ur ans."brienleint ans.​

Answer 1

Answer:

I think 2.25 M. is a correct answer

Answer 2

Answer:

0.35 M

Explanation:

R=k[A]

conc. of A = R/k

= 7 × 10 ^-4 ÷ 2 × 10 ^-3

= 0.35 M

Hope this helps.
