The reversible reaction is given: 2SO2 + O2↔ 2SO3. The velocity constant is equal to 0.2. The initial concentrations of SO2 and O2 are 2.5 and 1.5 mol / liter. 1. Calculate the initial velocity
2. Calculate the speed when 25% of SO2 is wasted.
3. How many times does the reaction speed increase, when we increase the pressure by 3 times.
4. Show how and how much the reaction speed changes when its development temperature drops from 30oC to 0oC. (Coefficient 3)

In an effort to address concerns about global warming, a power plant in portland, oregon is designed to take all of its exhaust gases from its boilers and recycle the co2 using the solvay process to make sodium hydrogen carbonate. the reaction is shown below. nh3(g) + h2o(l) + co2(g) + nacl(aq) → nahco3(aq) + nh4cl(aq) how many liters each of nh3 and co2 (both at stp) would be consumed to produce 3.00 kg of sodium bicarbonate? the volume of both nh3 and co2 would be
