Question

What is the temperature if 2L of 3moles HCl react with 2atm?

Answer 1

Answer:

$T=16K=-256.8\°C$

Explanation:

Hello!

In this case, according to the gas laws, we would be able to assume HCl can be modeled as an ideal gas for this calculation purpose; in such a way, we use the following equation to compute the temperature:

$PV=nRT\\\\T=\frac{PV}{nR}$

In such a way, we plug in moles, volume and pressure to obtain:

$T=\frac{2atm*2L}{3mol*0.08206\frac{atm*L}{mol*K}}\\\\T=16K=-256.8\°C$

Best regards!
