Video transcript

Hello everyone today, we have the falling problem. Consider the phase diagram of carbon dioxide below identify which labeled point is carbon dioxide most likely to behave as an ideal gas. So, as an ideal guess the definition is that they are ideal at very high temperatures and low pressure. According to this chart here, that is going to be at the bottom right where Point C is where the temperature is very high and the pressure is at its lowest, and so Point C is going to be our answer. I hope this helped, and until next time.

At a temperature of 700 K, the forward and reverse rate constants for the reaction 2 HI(𝑔) β‡Œ H2(𝑔) + I2(𝑔) are π‘˜π‘“=1.8Γ—10βˆ’3 π‘€βˆ’1sβˆ’1 and π‘˜π‘Ÿ = 0.063β€Šβ€Šπ‘€βˆ’1sβˆ’1. (b) Is the forward reaction endothermic or exothermic if the rate constants for the same reaction have values of π‘˜π‘“ = 0.097β€Šπ‘€βˆ’1sβˆ’1 and π‘˜π‘Ÿ = 2.6 π‘€βˆ’1sβˆ’1 at 800 K?
