Increase the temperature (explained in the Collisions Theory) causes the particles to move faster (and so collide more frequently) and also have a higher energy so the collision is more likely to end in a reaction (as two particles must have a minimum energy in order to react).
Increasing the surface area increases the number of particles that can collide and so increases the rate of reaction.
The same is true with increasing pressure/ concentration.
Adding a catalyst lowers the energy required for a reaction to occur so increases the rate of reaction.

Increasing the pressure will increase the reaction rate because it will force the particles to be closer together, and so the likelihood of particles colliding increases. Increasing the temperature can also increase the rate of a reaction because the particles will be more energised and more likely to move around and collide.

The major difference between real and nominal GDP is that real GDP

I am Lyosha [343]

C). Real GDP is adjusted for price level changes, whereas nominal GDP is not.

<h3>Explanation</h3>

The GDP of a country measures the total value of all final goods and services produced within that country in a certain period of time (typically a year.)

Real GDP is based on nominal GDP, but takes changes in the overall price level into account as well. That's why the two indice are so similar, except for that the value of real GDP but not nominal GDP can be compared over a period of many year to show economic growth.

Neither real GDP nor nominal GDP measure debt, which isn't part of the output of an economy.
Both real GDP and nominal GDP take the value of exports into account, as long as the good being sold abroad is made inside that country. Net export is also one of the four types of spendings on the output of an economy.
Only real GDP is adjusted for changes in the price level. <em>This point sets real and nominal GDP apart.</em>
Neither real GDP nor nominal GDP counts intermediate goods. To avoid counting the same good or service twice, both indice measure only the value of final goods and services.

If 1.00 g of a hydrocarbon is combusted and found to produce 3.14 g of co2, what is the empirical formula of the hydrocarbon?

photoshop1234 [79]

The combustion reaction is as expressed,

CxHy + O2 --> CO2 + H2O

The mass fraction of carbon in CO2 is 3/11. Hence,
mass of C in CO2 = (3.14 g)(3/11) = 0.86 g C.

Given that we have 1 g of the hydrocarbon, the mass of H is equal to 0.14 g.

moles of C = 0.86 g C / 12 g = 0.0713
moles of H = 0.14 g H / 1 g = 0.14

The empirical formula for the hydrocarbon is therefore, CH₂.
