For the following SN1 solvolysis reaction, select the correct rate equation and the overall reaction order (note: CH3OH is the s
sineoko [7]

Answer:

Explanation:

  • rate = K[(CH3)3CCl]
  • overall order is also first order

Since we are told that CH3OH is the solvent for the reaction, as such the rate law equation will only be written for (CH3)3CCl .

A galvanic cell at a temperature of is powered by the following redox reaction: 2Cr3 + 3Ca Suppose the cell is prepared with in
stira [4]

Answer:

2.13 V

Explanation:

The balanced equation of the reaction his;

2Cr^3+(aq) + 3Ca(s) -----> 2Cr(s) + 3Ca^2+(aq)

Since this is a galvanic cell then E°cell must be positive. It implies that calcium will be the anode and chromium will be the cathode since calcium is ahead of chromium in the electrochemical series.

E°anode= -2.87 V

E°cathode= -0.74 V

E°cell= E°cathode -E°anode

E°cell= -0.74 -(-2.87)

E°cell = 2.13 V

A phase change for carbon dioxide that occurs spontaneously at 20.°C and 1.0 atmosphere is represented by the balanced equation
Troyanec [42]

Answer:

The name of the phase change is;

Sublimation.

Explanation:

CO₂(s) + energy ⇒ CO₂(g)

Sublimation is the transition of a substance from its solid state to the gaseous state without first turning to a liquid due the high rate of absorption of of thermal energy of the substance such that the substance does not melt first.

As such sublimation is the endothermic process taking place at  a temperature and pressure lower than the triple point of the substance in the substance's phase diagram. The triple point is the lowest temperature and pressure at which a substance can exist as a liquid.
