Question 28 GCE_MODEL_QUESTIONS_VOL1 • 2020 • PHYSICS • objective

In a rigid 5.0\,L container at \(300\ \text{K}\) there are initially \(0.060\ \text{mol}\) of gas A and \(0.080\ \text{mol}\) of gas B. They react according to \(\text{A} + 2\text{B} \rightarrow \text{C} + \text{D}\) and the reaction proceeds until all of A is consumed. Assuming ideal behaviour and that the volume remains constant, calculate the final pressure of the gas mixture when the temperature is raised to \(350\ \text{K}\). (Take \(R = 0.0821\ \text{L\,atm\,K}^{-1}\text{mol}^{-1}\).)

Answer Options

A. 0.380 atm
Correct Answer B. 0.460 atm
C. 0.560 atm
D. 0.720 atm
Correct Answer
B
Correct Option:
0.460 atm
