Question

10 g of $C_2{H}_6$ is filled in a bulb having 1 litre capacity which can withstand a maximum pressure of 10 atm. At what temperature will the pressure of gas reach the bursting limit?

• A. $76{}^{\circ }\text{C}$
• B. $361.4{}^{\circ }\text{C}$
• C. $92.4{}^{\circ }\text{C}$
• D. $120{}^{\circ }\text{C}$

Answer 1

The correct option is C $92.4{}^{\circ }\text{C}$

Using the ideal gas equation we get:
$T=\frac{PV}{nR}=\frac{10\times 1}{\left(10/30\right)\times 0.0821}=365.4\text{K}=92.4{}^{\circ }\text{C}$
