OR
Contact process is used in the formation of sulphur trioxide, 2802(g) + O2(g) 250,(g).
The rate of reaction can be expressed as
- A[0] =2.5x10-moll's, then the rate of

Answer 1

mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density.
