How much heat is produced when 2.63 g of phosphorous and 40g of Bromine is allowed to react according to following equation
`P_(4(s))+6Br_(2(l)) rarr 4PBr_(3(g)), DeltaH=-486 kJ`

A

10.30KJ

B

20.6KJ

C

40.12KJ

D

5.63KJ

Text Solution

Verified by Experts

The correct Answer is:
A
`P_(4)+6Br_(2)rarr4PBr_(3)" "DeltaH=-486KJ`
Limiting Reagent = `P_(4)` excess reagent = `Br_(2)`
`124gmrarr-486KJ`
`2.63gmrarr?`
