Rate Law and Value of Rate Constant
1) The reaction 2NO(g) + Cl2 produces 2NOCl(g) was studied at -10 degrees C. The following results were obtained Rate = Delta[Cl2] over Delta t. [NO]0 (mol/L) 0.10, 0.10, 1.20 [Cl2]0 (mol/L) 0.10, 0.20, 0.20 Initial Rate(mol/L*min) 0.18, 0.36, 1.45 a) What is rate law? b) What is the value of the rate constant?
The reaction A produces B + C is known to be zero order in A and to have a rate constant of 5.0 x 10 superscript-2 mol/L x sec. @ 25 degrees C. An experiment was run at 25 degrees C where [A]0 = 1.0 x 10 superscript-3 M. a) Write the integrated law for this reaction b) Calculate the half-life for this reaction c) Calculate ...continues
Although they both have the same C2H6O chemical formula, dimethyl ether, CH3OCH3, boils at -25C while ethanol, CH3CH2OH boils at 76C. Why?
If 4.15g of TiO2(s), 5.67g C(s) and 6.78g of diatomic Chlorine react to the equation: 3TiO2(s)+4C(s)+6Cl2(g)---3TiCl4(g)+2CO2(g)+2CO(g) what is the maximum amount of TiCl4(g) that can be produced?
