Answer:
A. m and n are independent from the molar coefficients of the reactants in the balanced chemical equation.
B. m and n must be determined by experiment.
Explanation:
rate = k[H2O2]^m × [I-]^n
The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant.
Either the differential rate law or the integrated rate law can be used to determine the reaction order of reactants from experimental data.
Answer:
endormic
Explanation:
It occurs at a temperature and pressures below a substance's triple point on its phase diagram, which corresponds to the lowest pressure at which the substance can exist as a liquid
No, it won't. A substance will only precipitate if it is not soluble in an aqueous solution. If you look at the solubility rules, it indicates that all sulfates are soluble except for ions of Ba, Pb, Ca and Sr. Since Ag is not in the list, AgSO4 is soluble and will not precipitate.
Answer:
A liquid, at any temperature, is in equilibrium with its own steam. This means that on the surface of the liquid or solid substance, there are gaseous molecules of this substance. These molecules exert a pressure on the liquid phase, a pressure known as vapor pressure.
In chemistry, when we talk about dry basis, we talk about a state in which the presence of water in a gaseous state is denied for the calculation. So vapor pressure equals zero.
When we talk about the wet basis, the presence of water in the steam is considered for the calculation, which normally is expressed as a percentage or moisture.
In summary, for a gas mixture steam:
- For dry basis, we just have <em>component A, component B....</em>
- For wet basis, we have <em>water vapor, component A, component B...</em>
So, in wet basis we have an extra component (water).
Assuming we only have 2 components in our steam, and being X the molar fraction of eact component:
- For dry basis: Xa + Xb = 1................................. Xa = 1 - Xb
- For wet basis: Xa + Xb + Xwater = 1 .............Xa = 1 - Xwater - Xb
For dry basis the mole fraction of A it is obtained by subtracting the molar fraction of B from one. And for wet basis, we have to substract the molar fraction of B <u>AND </u>the molar fraction of water vapor. So, logically, the mole fraction Xa will be less for wet basis.
