Title: Unit Four Questions
Post by: burbs on June 15, 2011, 08:42:13 pm
No time to waste.

Consider the following equation

2H2(g) + O2 (g) -> 2H2o(g) /\H=-484 kJ/mol

Which of the following will decrease the rate of the reaction?
a) increasing the volume
b) increasing the temperature at a constant volume
c) increasing concentration of reactants at constant temperature
d) adding a catalyst.

I know it's not D or B.

Good idea mate, after a torrid unit 3 exam, all I can look forward to is the hours of study I will spend studying unit 4 chemistry.

Did you do well on the exam?

It tore me a new one, just the kick up the ass i needed to smash unit 4 and all other subjects haha

Haha, were you joking about getting a head start? o.o If not, I'm certainly in the race too. Considering I didn't fair too well, I'd better prevent what happened this exam ever happening again =(
