Q3/ A 100 ml of 0.05 M concentration of ethyl acetate was mixed with 100 ml of 0.05 M of NaOH. After 10 min, the concentration of NaOH was 0.0435 M and after 30 min the remaining concentration of NaOH = 0.041 M. Calculate: a)- The rate constant of this reaction? b) - The half-life time (t0.5) Of this reaction?

Please solve part c and d only

I want you to give me step by step solution and describe everything.

Using the graphic below as a reference, describe what happens to a reversible reaction as it attains equilibrium.

What is the concentration of A after 20.5 minutes for the reaction A → Products when the initial concentration of A is 0.800 M? (k = 0.00651 M/min)

(a) Consider the mass transfer-limited reaction: A → 2B DAB = 0.01 cm²s-1 What would your concentration (mole fraction) profile look like as a function of distance (i.e. z/8)? What is the flux of A?

Please help!!!

The kinetics of the hydrolysis of methyl methanoate, CH;COOCH;, in aqueous solution were investigated by measuring the concentration of the ester after different time intervals. The reaction was found to be first order in the concentration of the ester. Use the data below to determine the rate constant for the reaction. time (t/s) concentration (c/mol.dm-3) 1800 3600 5400 7200 9000 0.300 0.191 0.135 0.081 0.055 0.035

Problem IX (10 p): Consider the isomerization of compound A from its cis to its trans isomer at 298 K, which is first order in both directions: ki cis-A = trans-A k2 The rate constant for the forward reaction is k1 = 4.2 × 10* s', and the rate constant for the reverse reaction is k2 = 2.1 × 10-ª s-1. %3D a) Calculate the equilibrium concentrations [cis-A]eq and [trans-A]eq, assuming that at time t= 0 all of A was in the cis-form, i.e., [cis-A]o = [A]o. (Hint: Use the fact that at any time, [cis-A] + [trans-A] = [A]o.) %3D b) Which reaction is spontaneous, the forward reaction or the reverse reaction? Provide your reasoning. Total /100 p

The rate of a certain reaction is given by the following rate law:   rate =kNO2O2 Use this information to answer the questions below.   What is the reaction order in NO?   What is the reaction order in O2?   What is overall reaction order?   At a certain concentration of NO and O2, the initial rate of reaction is 5.0 x 104 M / s. What would the initial rate of the reaction be if the concentration of NO were doubled? Be sure your answer has the correct number of significant digits. Ms The rate of the reaction is measured to be 40.0 M / s when [NO] = 0.57 M and [O2] = 2.0 M. Calculate the value of the rate constant. Be sure your answer has the correct number of significant digits. =k⋅M−2s−1
