Question

Hydrogen gas reacts rapidly with oxygen gas in the presence of a platinum catalyst. Which equation correctly represents this reaction?

Upper H subscript 2 (g) plus upper O subscript 2 (g) plus upper P t right arrow upper H subscript (g) plus upper O subscript 2 (g).
Upper H subscript 2 (g) plus upper O subscript 2 (g) right arrow upper H subscript 2 (g) plus upper O subscript 2 (g) plus upper P t.
2 upper H subscript 2 (g) plus upper O subscript 2 (g) right arrow with upper P t above it, 2 upper H subscript (g) plus upper O subscript 2 (g) plus upper P t.
2 upper H subscript 2 (g) plus upper O subscript 2 (g) right arrow with upper P t above it, 2 upper H subscript (g) plus upper O subscript 2 (g).

Answer 1

D. 2 upper H subscript 2 (g) plus upper O subscript 2 (g) right arrow with upper P t above it, 2 upper H subscript (g) plus upper O subscript 2 (g).
