Answer:
Activation energy for the uncatalyzed reverse reaction = 103 kJ/mol
Explanation:
Activation energy decreases from = 56 kj/mol to 35 kj/mol
products = 78 KJ lower in energy than reactants
Activation energy for the uncatalyzed reverse reaction = 103 kJ/mol
attached below are the sketches of approximate energy-level for both catalyzed and uncatalyzed reactions
Answer:
It will take 8.09 seconds to cover 235 meters by car with speed of 65 mile/h.
Explanation:
Speed of the car = 65 mile/h = 65 1609.34 m/h = 104,607.1 m/h
1 mile = 1609.34 m
Distance covered by the car in t time = 235 m = mile
t = 0.002246 h
1 hour = 3600 seconds
0.002246 h = 0.002246 h × 3600 seconds = 8.09 seconds
It will take 8.09 seconds to cover 235 meters by car with speed of 65 mile/h.
