When we're talking about something that's emerging, we're talking about a characteristic of a certain object we're observing which couldn't be directly inferred from its known constitutional parts.
If we know water is made out of oxygen and two hydrogen molecules, we cannot predict certain qualities it has. What we need to know and what is important is that we also know the interaction between the constitutional parts of our object so that we can properly explain the new observed characteristic.
Answer: The rate of the forward reaction increases.+The concentration of
products increases. /The rate of the reverse reaction increases.+The concentration of products decreases.
Explanation: I got this right on Edmentum.
Since the question manages to include moles, pressure, volume, and temperature, then it is evident that in order to find the answer we will have to use the Ideal Gas Equation: PV = nRT (where P = pressure; V = volume; n = number of moles; R = the Universal Constant [0.082 L·atm/mol·K]; and temperature.
First, in order to work out the questions, there is a need to convert the volume to Litres and the temperature to Kelvin based on the equation:
250 mL = 0.250 L
58 °C = 331 K
Also, based on the equation P = nRT ÷ V
⇒ P = (2.48 mol)(0.082 L · atm/mol · K)(331 K) ÷ 0.250 L
⇒ P = (67.31 L · atm) ÷ 0.250 L
⇒ P = 269.25 atm
Thus the pressure exerted by the gas in the container is 269.25 atm.
