Calculate ΔS(for the system) when the state of 2.00 mol diatomic perfect gas molecules, for which Cp, m (7/2)R, is changed from 25 C and 1.50 atm to 135 C and 7.00 atm. How do you rationalize the sign of ΔS?

first one is the correct answer

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

yes
