What would happen to the rate of a reaction with rate law rate k NO2H2 if the concentration of H2 were halved
The rate would be four times larger.
Impossible.
How many hydrogen ions in a solution with a pH of 4.0
pH = -log[H+] Hence [H+] = 10^-pH = 10^-4 = 1 x 10^-4 mole of
H+
Now 1 mole of H+ = 6.022 x 10^23. Hence 1 x 10^-4mole = 6.022 x
10^19 H+ ions.
How is the Hvap used to calculate the mass of liquid boiled by 1 kJ of energy
1kJ x 1/deltaHvap x g/mol liquid.
What does stressing an equilibrium system mean how is stress applied
Stressing an equilibrium simply means that the physical properties in which already exists are balanced. Stress can be applied by either changing the pressure or the volume or temperature.
What is the rate of a reaction that follows the rate law rate kAmBn where k 0.2 A3 M B3 M m1 n2
What are the phase change processes taking place when a substance is in equlibrium between liquid and gas phase
This is boiling - liquid transformation in gas.
