Consider the reaction below. C2H4(g) + H2(g) to C2H6(g) Which change would likely cause the greatest increase in the rate of the
2 answers:
Answer: Option (d) is the correct answer.
Explanation:
In the given reaction, greatest increase in rate of reaction only occur when we increase the temperature and also increase the pressure.
This is because increase in pressure will bring the molecules closer to each other whereas increase in temperature will help in more number of collisions between reactant molecules.
Thus, this will lead to increase in formation of products. Hence, we can conclude that rate of reaction will increase with increase in temperature and increase in pressure.

Answer:
Explanation:
The ideal gas law equation is an equation that relates some of the quantities that describe a gas: pressure, volume and temperature.
The equation is:
where
p is the pressure of the gas
V is the volume of the gas
n is the number of moles of the gas
R is the gas constant
T is the absolute temperature of the gas (must be expressed in Kelvin)
Here we want to solve the equation isolating p, the pressure of the gas.
We can do that simply by dividing both terms by the volume, V. We find:
So, we see that:
- The pressure is directly proportional to the temperature of the gas
- The pressure is inversely proportional to the volume of the gas
