Answer:
101
Explanation:
Provided that
And,
Now we expect the same
{S} (0.1mM)
This determines that 
generates a higher rate of product formation as compared to the 
So we can easily calculate the 
for either of or as we know that Tube 1 is and tube 2 is
As we know that
As the rates do not include any kind of units so we do not consider the units for
Now the calculation is
= 100.5
≈ 101
No. of moles of calcium chloride = molarity × volume of solution in L
No. of moles of calcium chloride = 2.5 ×0.5 = 1.25 mole
No. of moles of calcium chloride = mass of calcium chloride / molar mass of calcium chloride
1.25 mole = mass of calcium chloride / 110.98 g/mol
mass of calcium chloride = 1.25 ×110.98 = 139 g
As the volume increases, there is more space so the average distance between the gas molecules also increases.
Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection
Following three <span>things when applied could make the reaction to occur more quickly;
1) Increasing Temperature:
Increase in temperature increases the Kinetic energy of molecules. This results in increase in the velocity and rate of collisions between reactants. Hence, greater the number of collisions between reactants per time greater will be the probability of formation of product per unit time.
2) Grinding Calcite:
Grinding of Calcium carbonate results in the increase of surface area of calcite. So greater the surface area greater is the exposure of Calcium carbonate to HCl molecules, hence the rate of formation of product increases.
3) Using Catalyst:
Very important. Catalyst when used decreases the activation energy and increase the rate of reaction by following methods.
a) Providing new pathway
b) weakening the bonds
c) providing surface area
d) holding up the reactant close to each other.</span>
