Answer: The balanced equation for overall reaction is:
(CH3)3AuPH3 ----> C2H6 + (CH3)AuPH3
Explanation:
The reaction mechanism is given as follows:
Step 1: (CH3)3AuPH3 ↔ (CH3)3Au + PH3 (fast)
Step 2: (CH3)3Au → C2H6 + (CH3)Au (slow)
Step 3: (CH3)Au + PH3 → (CH3)AuPH3 (fast)
To balance this equation, firstly, we conduct proper atom count for each steps of the reaction mechanism.
It is important to note that for a reaction that involves several steps, the rate law is normally derived from the slow step ( which is step2 from the above mechanism).
Therefore, the balanced chemical equation for the overall reaction is:
(CH3)3AuPH3 ----> C2H6 + (CH3)AuPH3
Answer: At very low temperatures, gases expand less for a given pressure change than they do at high temperatures.
Explanation:
A hiker climbs to the top of a mountain at rate of 0.5 m/hr. The speed of hiker is 1.3 x 10⁻⁴ m/s and the velocity of the hiker is 1.3 x 10⁻⁴ m/s west.
Speed is a scalar quantity. It is used to measure the distance traveled in a period of time. It is represented by -
s = d/Δt
where,
s = speed
d = distance
Δt = change in time
Velocity is a vector quantity. It is used to measure the change in position, that is, displacement over the change in time. It is represented by -
v = Δs / Δt
where,
v = velocity
Δs = change in position/displacement
Δt = change in time
The standard unit of velocity and speed both is m/s.
