What amount of time is required for the concentration of A to decrease from 0.800 M to 0.180 M in the zero- order reaction A->B? (k = 0.0567 M*s1)

The reaction A+B → C was investigated in a series of experiments with different initial concentrations of the two reactants. The following initial rates were observed. What is the overall reaction order? O 0 05 02 0 1 O 3 04 Experiment 1 Experiment 2 Experiment 3 Initial [A] 0.10 M 0.20 M 0.20 M Initial [B] 0.10 M 0.10 M 0.20 M Initial rate 1.60 x 10-2 mol L-1 s-1 3.20 x 10-2 mol L-1 5-1 3.20 x 10-2 mol L-1 5-1

In 2nd order reaction 2OH →→ H2O + O k = 1.47 x 1010 M-1 s-1. There is an initial OH concentration of [OH]0 = 1.88×10−4M.     a)How long will it take for the OH concentration to decrease to 6.0997×10−5M?

For a first order reaction A→B, what will be the nature of the graph if [A] is plotted against time, t ? Straight line with a positive slope Straight line with a negative slope A curve showing exponential decrease A curve showing exponential increase

1)The reaction A -> product is second order. If the initial concentration of A is 0.436 M and, after 52.8 seconds have elapsed, the concentration of A has fallen to 0.0476 M, what is the rate constant of the reaction?     2) consider the following reaction at equilibrium.2CO2 (g) ->_<-- 2CO (g) + O2 (g)  H° = -514 kJLe Châtelier's principle predicts that the equilibrium partial pressure of CO (g) can be maximized by carrying out the reaction ________.
