Increasing the pressure will mean that these particles will collide more frequently to yield the products hence driving the forward reaction.
According to the collsion theory, reaction occurs as a result of collision between reactants in a system. Now we have the reaction; 2SO2(g) + O2(g) <==> 2SO3(g) + 392 kJ.
We can see that there are more particles on the left hand side than on the right hand side. Increasing the pressure will mean that these particles will collide more frequently to yield the products hence driving the forward reaction.
Now;
2 moles of SO3(g) produces 392 kJ of heat
1 mole of SO3(g) produces 1 mole * 392 kJ /2 moles
= 196 kJ

Gases, fluids, and other solids in contact with a moving object will produce heat due to friction. The contact between molecules or atoms present in gases, fluids, and other solids creates energy and it may be in the form of heat.
The answer is: Heat flow
b. Wearing goggles
c. Pushing glass tubing, thermometers, or glass thistle tubes through a rubber cork
d. Pointing the mouth of a test tube that is being heated away from you and others
e. Knowing where the fire extinguisher and eyewash stations are located
Balance the equation and state which substance is oxidised and which is reduced
Explanation:
To balance the chemical equation for the extraction of iron from iron(III) oxide using carbon, you need to ensure that the same number of each type of atom appears on both sides of the equation. Here's the balanced equation:
2Fe₂O₃ + 3C -> 4Fe + 3CO
Now, let's determine which substance is oxidized and which is reduced:
1. Iron (Fe) undergoes a change in oxidation state from +3 in iron(III) oxide (Fe₂O₃) to 0 in elemental iron (Fe). It is reduced because it gains electrons, going from a higher positive oxidation state to zero.
2. Carbon (C) in carbon (C) undergoes a change in oxidation state from 0 to +2 in carbon monoxide (CO). Carbon is oxidized because it loses electrons and goes from an oxidation state of 0 to +2.
So, in this chemical reaction:
- Iron is reduced (it gains electrons).
- Carbon is oxidized (it loses electrons).
b. 3.0
c. 0.20
d. 20
