Answer: A
Trust me or don’t I just know it
Reaction B has a higher activation energy than reaction A.
Increasing the temperature of gas will probably ruin whatever it’s in. Such as a car, the increase of temperature will ruin the car price by peice.
Because they are in group 1 of the periodic table (alkali metals), they all have the same properties. They each are malleable, good conductors of electricity, highly reactive, and have low melting points.
Since you are provided with the pressure and initial volume and told a standard temperature, you should use the Combined gas law. This is (P1 V1)/ T1 = (P2 V2)/ T2
STP is 273 k for temperature, so plug in the values.
(3.5 Pa * 25 L)/ 273 K =1.3 Pa * X L)/ 273 K.
(this is the left side>)0.32051= 1.3 X/ 273. Multiply both sides by 273 to get rid of it on the right, which leaves you with
87.4999 = 1.3 X. Divide both sides by 1.3 and there you go,
67.308 L
