he have great passive and u have 71 armor with only quint and seal armor runes

Riven won't even poke you, but placing Malphite top is like placing a passive creep farmer top; He won't die, but he won't kill either. He will just basically organize a farmfest for both parties for 20 minutes long.
The only time when you should place Malphite top is when your jungler has enough burst. I don't even see how Malphite has any chance to beat Riven top 1v1. Malphite is just a creep farming bot top, 'nuff said.
