Answer:
Answer in explanation
Explanation:
A. Heating the mixture
Before we can explain the effect of a temperature increase, we need to know the type of reaction it is on temperature basis. As heat is produced, this type of reaction is an exothermic reaction. An exothermic reaction is one in which heat is released into the environment. As such, increasing the temperature of an exothermic reaction leads to more reactants being formed. The equilibrium will thus favor the backward reaction
B. Adding an excess of carbon monoxide
This means we are adding more reactants to the mix. This causes an increase in the available reactants necessary for the reaction to take place making it possible for more product to be formed. This thus favors the forward reaction
C. Removing the methanol as it is formed also favors the forward reaction. This favors the forward reaction as there is allocation for more product to be formed
D. Adding a substance that reacts with carbon ii oxide means less reactant availability which makes it possible for the equilibrium to favor the backward reaction as less reactant is available to give more product.
Answer:
0.1077 grams
Explanation:
First we will employ the ideal gas law to determine the number of moles of nitrogen gas.
PV=nRT
P=2 atm
V=20L
R=0.08206*L*atm*mol^-1*K^-1
T=323.15 K
Thus, 2atm*20L=n*0.08206*L*atm*mol^-1*K^-1*323.15K
K, atm, and L cancels out. Thus n=2*20mol/0.08206*323.15=1.5 moles
Lastly, we must convert the number of moles to grams. This can be done by dividing the number of moles by the molar mass of nitrogen gas, which is 14 grams.
1.5/14=0.1077 grams

This is a Charles' Law problem: V1/T1 = V2/T2. As the temperature of a fixed mass of gas decreases at a constant pressure, the volume of the gas should also decrease proportionally.
To use Charles' Law, the temperature must be in Kelvin (x °C = x + 273.15 K). We want to solve Charles' Law for V2, which we can obtain by rearranging the equation into V2 = V1T2/T1. Given V1 = 25 L, T1 = 1200 °C (1473.15 K), and T2 = 25 °C (298.15 K):
V2 = (25 L)(298.15 K)/(1473.15 K) = 5.1 L.
