temperature, reactant A reacts according to the chemical equation: sk=
A(g) +B(2) ►
At 500 °C, the rate of the reaction increases with concentration of A as follows: =310
[A](M)
Rate(M/s)
= 152
1.2x10-2
(1) Determine the order of the reaction and write the rate expression. R=k [A]
(2) Calculate the rate constant, and give its units
k= = 1,24 104 (5!M²
(3) Calculate the rate for a 0.0020 M concentration of A. R = 1,27104
