A student obtained the following data for the conversion of methyl isonitrile to acetonitrile in the gas phase at 250 °C.
CH3NC(g)--->CH3CN(g)
(1) What is the half-life for the reaction starting at t = 0 s?_________ s
What is the half-life for the reaction starting at t = 169 s?________s
Does the half-life increase, decrease or remain constant as the reaction proceeds? _________(increase/decrease/remain constant)
(2) Is the reaction zero, first, or second order? _______(zero/first/second)
(3) Based on these data, what is the rate constant for the reaction?________ s-1
(please help me no one yet has been able to answer these questions correcty)
Consider this prototypical nucleophilic substitution shown in the box. The effect of doubling the volume of solvent would be to multiply the reaction rate by a factor
A flask containing a mixture of compounds A and B are decomposed by first-order kinetics. The half-lives are 45 min for 15 min for A and B. If concentrations at the beginning of A and B are equal, how long will it take for the concentration of A t..

discribe how to prepare this solutions show all work and calcualtion? a) 50mL of asolution containing 0.15M malonic acid [CH2(COOH)2 plus 0.02 manganese sulfate [ MnSO4] b) 100 mL of 0.08M sulfuric acid
A gas vessel is attached to an openend manometer containing a nonvolatile liquid of density 0.791g/mL. The difference in heights of the liquid in the two sides of the manometer is 43.4 cm when the atmospheric pressure is 755 mmHg.
An X-ray photon of wavelength 0.930 strikes a surface. The emitted electron has a kinetic energy of 940 . What is the binding energy of the electron in kJ/mol
Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written: 2HCl(aq)+Na2Co3(aq) --- 2NaCl(aq)+H2O(I)+CO2(g)
Two questions about using the normality equation N1V1=N2V2 to calculate the amount of titrant needed to neutralize an analyte
