What is the correct rate law for the following reaction? 2 NO2(g) + F2(g) → 2 NO2F(g) rate = kf(NO)2 rate = -kf(NO2)2(F2) rate = kf(NO2)2(F2) rate = -kf(F2) Not enough information is available to determine the rate law.

Physics
Understanding Newton's First and Second Laws, why do all objets near Earth accelerate at a constant rate "g"? I'm very confused, is it something about how inertia keeps the objects accelerating? Please help , thank you.

rate = -delta [N2O5]/delta time rate = (0.218-0.0296)/282 = ? Then rate = k[A]. Calculate k.

Chemistry
The rate equation is rate = k(CO)^x(O2)^y. Divide rate 2 by rate 1. 0.226/0.113 = 2 and 2 = (0.300)x(0.150)y/(0.150)x(0.150)y Note that 0.150y cancels with 0.150y and leaves just 2= (2)x and x must be 1. Do the same thing for rate 3 divided by rate 2 and determine y. You ...
