Use this graph to answer the following questions: What is the half life of the reaction? 4/2 %3D Round your answer to 2 significant digits. Suppose the rate of the reaction is known to be first order in Cl,0,. Calculate the value of the rate constant k. k = Round your answer to 2 significant digits. Also be sure you include the correct unit symbol. Predict the concentration of Cl,0, in the engineer's reaction vessel after 0.120 seconds have passed. [q,0.] = [0M %3D Assume no other reaction is important, and continue to assume the rate is first order in Cl,Og. Round your answer to 2 significant digits.

Given that the rate constant for the decomposition of hypothetical compound X from the image is 1.60M^-1•min^-1, calculate the concentration of X after 20.0 min.

Determine the average rate of change of B from t = 0 s to = 362 s. A → 2B rate = M/s Time (s) 0 181 362 Concentration of A (M) 0.720 0.425 0.130

The rate of a reaction is monitored by measuring the number of moles of product that form per liter per second. The data obtained are listed in the table below. Using this data, mathematically determine the order with respect to each reactant, the overall order of the reaction, determine the rate constant, k, with units, and write the complete rate law. Experiment [X], M [Y], M Rate, Msec-1 1 0.0500 0.0850 0.643 2 0.0300 0.0850 0.386

The rate constant for the second order reaction 2 NO2 - 2 NO + O2 is 0.24 M's. If a 1.38 M sample of NO2 reacts for 47.7 seconds, what concentration of NO2 wil remain? Report your answer to two decimal places. |Al = - kt +|Alo InJAl = - kt + InlAlo TAI = kt + TAlo

The reactant concentration in a first-order reaction was 5.80×10−2 M after 40.0 s and 1.60×10−3 M after 70.0 s . What is the rate constant for this reaction?   Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash.

A reaction that is second-order in reactant A has [A]o = 0.200 M. The half-life is 45.6 sec. What is [A] after 3.00 min? Report the molarity in standard notation with 3 significant figures and do not include units (M).

Consider a first order reaction AB }A+ B If the reaction is 34% complete at the end of 39 s, what is the length of the half-life of this reaction in seconds? Use 2 significant figures in your answer. Do not include the unit.
