A chemical reaction `2A rarr 4B+C`, in gaseous phase shows an increase in concentration of `B` by `5xx10^(-3) M` in `10` second. Calculate:
(a) rate of appearance of `B`,
(b) rate of the reaction,
(c ) rate of disappearance of `A`.

Explanation

To solve the problem step by step, we will calculate the required values based on the given reaction and the change in concentration of B.

### Given Reaction:
\[ 2A \rightarrow 4B + C \]

### Given Data:
- Increase in concentration of B: \(\Delta [B] = 5 \times 10^{-3} \, M\)
- Time interval: \(\Delta t = 10 \, s\)
