Question

Given the reaction

SO2 (g) + NO2(g) <=> NO3 (g) + NO (g)    [delta H rxn= -40.8 kj/mol]

According to Le Chatelier's principle, predict the effect of the following'

Increase in partial pressure of NO2 (g) --effect on Kc? No effect, increase, not enough information, decrease?

Increase in temperature-effect on [NO]?

decrease in total volume- effect on [SO2]?

Decrease in partial pressure of products-effect on [SO2]?

add Pt metal catalyst - effect on products [NO3] and [NO]?

For every question answer: No effect, increase, decrease or not enough info??
