To increase the rate of a reaction, you can either do any of the following:
-increase the temperature
-increase concentration of the aqueous reactant
-increase pressure of the gas
-use a catalyst
-increase surface area of the solid reactant
From these, the engineer should therefore do C. Adding a catalyst speeds up the reaction without really joining the reaction.
Convert the mass to moles .
85.1 g ÷ 20.18 g/mol = 4.21704658
convert the moles to molecules
4.2170 mol × 6.022^23 molecules/mol = 2.539^24
I think it was sue to she has all the details to seem like it was her
<span>Use the combined gas law. It's (P1V1)/T1 = (P2V2)/T2.
P1 = 501 kPa, V1 = 5.2 L, T1 = 298 K*; P2 is your unknown, V2 = 7 L, T2 = 372 K*.
*In problems like this, you must always convert Celsius to Kelvin by adding 273 - or 273.15 if you want to be more specific. I used 273.
you should get 465.8387 kPa.</span>
