Answer:
0.675 mol
Explanation:
Step 1: Write the balanced equation
2 Al + Fe₂O₃ ⇒ 2 Fe + Al₂O₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of Fe to Al₂O₃ is 2:1.
Step 3: Calculate the moles of Al₂O₃ produced when 1.35 moles of Fe are produced
We will use the established molar ratio.
1.35 mol Fe × 1 mol Al₂O₃/2 mol Fe = 0.675 mol Al₂O₃
Answer:
Increase the concentration of the reactants.
Explanation:
This question seems vague, but to put it simply, the reaction rate decreases with a decrease in temperature, so we need to find a way to increase the reaction rate again. When you lower temperature, the molecules are slower and collide less. So therefore, in other words, we need to find a way to increase the rate of collisions between molecules. When the temperature drops, if we increase the concentration of the reactants, we are able to increase the rate of collisions between molecules. As a result, reaction rate is increased once again.
Answer:
2334.1136 Joules
Explanation:
Q= 65.6 g (4.186)(8.5)
If it's suppose to be in kilograms, the answer will be 2.3341136 Joules.
The differential rate expression for the rate of change in the concentration of B with time is
-rB = dCB/dt = kCB^n
where k is the rate constant and
n is the order of the reaction
This is assuming that the rate is only affected by the concentration of B and the order of the reaction is in the nth order.
