what is the effect of temp on the process of osmosis

Rise in temperature increases the molecular movement, thereby increases the rate of osmosis. Osmotic pressure is also directly proportional to temperature, as 
$$\begin{gathered} \mathrm{\pi } = \mathrm{iCRT} \\ \mathrm{where} \\ \mathrm{\pi } - \mathrm{osmotic} \mathrm{pressure} \\ \mathrm{i}- \mathrm{Van}\text{'}\mathrm{t} \mathrm{Hoff} \mathrm{Factor} \\ \mathrm{C}- \mathrm{concentration} \\ \mathrm{R}-\mathrm{gas} \mathrm{constant} \\ \mathrm{T} -\mathrm{temperature} \end{gathered}$$
