What is the concentration of a reactant after 28.5 s if the initial concentration is 0.150 M and the rate constant is 5.4 x 10⁻² s⁻¹?

Some measurements of the initial rate of a certain reaction are given in the table below. [N:] N2| |H2| initial rate of reaction 0.768 M 2.48M 0.0363 M/s 0.768 M 0.466M 0.00128M/s 0.209M 2.48M 0.00988 M/s Use this information to write a rate law for this reaction, and calculate the value of the rate constant k. Round your value for the rate constant to 3 significant digits. Also be sure your answer has the correct unit symbol. rate = k ||| x10 k =

Study the reactions. I. N2 (g) + O2(g) → 2NO(g) II. CO(g) + 02(g) → 2CO2 (g) III. Na(s) + HCI(1) → 2NACI(aq) + H2(g) What factor would only affect the rate of the third reaction? the pressure of the reactants the temperature of the reactants the concentration of the reactants the surface area of the reactants

Consider the following general reaction for which gases A and B are mixed in a constant volume container: A(g) + B(g) -> C(g) + D(g) Match what happens to the rate of the reaction under the following changes: (consider each change separately) v all of gas B is removed from the container more gas A is added to the container the temperature of the container is increased there is no change to the reaction rate ya catalyst is added to the container I. the reaction proceeds at a faster rate v gas D is also added to the container the reaction proceeds at a slower rate II. some of gas B is removed from the container Iy the reaction does not proceed at all the volume of the container is increased
