As velocity = displacement /time
Then dispalcement=150 km = 0.15 m
time=1700 s
velocity= displacement / time
= 0.15/1700
=0.0000882353 m/s
Answer:
it is 600 so the answer is b
Explanation:
Answer:
It is reevaluated
Explanation:
Because of this new evidence, the theory can change, so the scientists must reevaluate the theory
Answer:
D) Rate = K [NO2][Cl2]
Explanation:
2 NO2 + Cl2 → 2 NO2Cl (overall reaction)
NO2 + Cl2 → NO2Cl + Cl (slow)
NO2 + Cl → NO2Cl (fast)
The rate-determining step is the slowest step in a reaction mechanism. Because it is the slowest, it determines the rate of the overall reaction.
Rate of reaction is typically given as;
Rate = K [Reactants]
In the slow step i the reaction mechanism, the reactants are; NO2 and Cl2. Since both are not intermediates, there is no need for further working out.
Rate = K [NO2][Cl2]
