for second order
1/ [A] = Kt + 1/[A0]
K = 11.88 x 10-5 mol-1 L s-1
t = 3.03 h = 10908 s
[A0] = 0.28 mol L-1
[A] = ?
1 / [A] = 11.88 x 10-5 x 10908 + 1/ [0.28]
1 / [A ] = 1.296 + 3.57
1 /[A] = 4.866
[A] = 0.20 mol L-1

please help me with both. TIA The following chemical reaction: A → products shows zero order kinetics with respect to A; rate = k[A]º. if k = 9.65 x 10-3 moll's and the initial concentration of A is 0.622 mol L-1, what is the half life of this reaction in minutes? You have 5 attempts at this question. Remember: if you want to express an answer in scientific notation, use the letter "E". For example "4.32 x 104 should be...
1-The rate constant of a chemical reaction was measured at several temperature values and a plot of ln k (on the y-axis) was plotted against 1/T (on the x-axis, temperature was measured in Kelvin). If the slope of the plot was -9.21 x 103 K and the y-intercept was 13.0, what is the activation energy (EA) of the reaction in kJ mol-1? 2-In an enzyme-catalyzed reaction, the rate of the reaction depends on which of the following at very low...
What is the molar solubility (in mol L-1) of a salt in pure water with general molecular formula MX (where M is a cation and X is an anion) that has Ksp = 1.57 x 10-8 ? You have 5 attempts at this question. Remember: if you want to express an answer in scientific notation, use the letter "E". For example "4.32 x 104 should be entered as "4.32E4" Answer: Check What is the molar solubility (in mol L-!) of...
